.303 British: Reeellly light gallery type loads?

[MOC031]

Short explanation: my younger brother suffered a whiplash injury bad enough he was designated 100% disabled for work and sent into early retirement. Amongst the other stuff, his specialist told him his days of shooting his centerfire rifles are over. Even the hand shock from shooting his recurves aggravates the injury, but he built himself a 45 lb long bow for hunting and finds that tolerable. His rimfire rifles he can still shoot with no problems.

So... one of his rifles is a No. 4 Mk1 Lee Enfield I gave him a few decades ago. He's heading over here in a few days, and I want to put together a REALLY light load that he can try and see if he can shoot it without irritation. Something below "The Load" levels of velocity and resulting recoil. I'm hoping that something with a velocity of about 700 - 800 fps with either one of my 175/185 grain moulds will be something that doesn't aggravate his neck injury. At least that would allow him to shoot targets/gophers, etc out to hopefully 50 yards at least.

I'm thinking/guessing of starting with 5 grains of Bullseye, W231, Clays, 700-X, Red Dot, Unique, C-300 (some of what I have on hand) to see how that goes and what the chronograph tells me. I'll be checking the bore after every shot for a bit to ensure I haven't stuck a bullet in the bore before the next round goes in the chamber.

Before I start assembling loads... anybody out there who's already done something similar in .303 British with similar weights of cast bullets? How did it go and what kind of velocities and accuracy did you get?

[Outpost75]

I used NOE version of 314299 without the GC, lubing with Lee Liquid Alox and loading bullets as-cast and unsized. 5 grains of any of the powders you mentioned will get the bullet out of the barrel OK. No filler is necessary with the easily ignited flake pistol or shotgun powders. I got best accuracy with 6 grains of Red Dot or 700X, which gave a bit over 1000 fps. I set the battlesight at 500 yards to zero at 100 yards. Accuracy was as good as military surplus ball ammo. Increasing the charge got higher velocity and was louder, but did not improve grouping. I would work in the range of 5-7 grains and see which your rifle likes.

Above 8 grains bullets will lead unless gas checked.

[jim147]

I haven't tried going that slow but do you have any .32 H&R boolits around? Might be able to make a nice light accurate combo with that.

[longbow]

I haven't gone that light but I do have a couple of lighter than normal boolits I've used over moderate charges of IMR4227. They'd likely recoil a bit much for your purpose but...

One mould is the Mihec 316410 130 gr. solid or 126 gr. HP. It shoots very well from my guns but does not feed from the magazine due to short boolit.

The other is a homemade mould clone of the Ness Safety Bullet I made when there was a group buy going on. I wanted it but was concerned that the enormously deep HP pin would be a problem with sticking so I made a push out smooth sided mould with same pin and found that it cast really well and didn't stick! In the end I decided not to get in the group buy and just used my mould. This one is a 150mgr. HP and it feeds just fine.

Point being if you go for a really light boolit it may not feed. I'd suggest the Lee 0.312" 155 or 165 gr. for .303.

[Bloodman14]

If plinking at paper or groundhogs, how about the Lee 90gr. semiwadcutter on top of Red Dot or Unique? No recoil, super accurate and fun to shoot.
About the injury, can a chiropractor help?

[LAGS]

If you want to shoot the .303 at very short ranges , get yourself a Chamber Adapter to shoot pistol ammo out if it.
I bought ones for my .303 , .308 , .30-06 and 7.62x54.
I shoot .32 S&W and .32 S&W long but haven't tried .32 H&R yet.
They are so quiet that they sound quieter than my .22s.
At .50 yards they are accurate once you adjust your sights for the lighter handgun rounds.
I found that it is easier to reload the handgun ammo that I use with a Lee Classic Reloader than to try and Reduce Rifle loads down to mouse fart loads.
Your rifle loads can also be loaded the lighter pistol .32 caliber Boolits that makes a good Gallery load.

[Jniedbalski]

You can use a 32 pistole bullet 90 to 100 gr with 3.2 of bullseye. This is a very good 50 yard load just like a really good 22 rifle. I tumble lube with Alox or white label 45/45/10. This is a very good load in 308,303 7.62x54r . I use the lee tl.314 90 gr swc. I also use the lee .311 100 gr 2R in my 308.sized .311 in 308. The 7.62x54R and 303 I use the .314 90 gr swc not sized load as it dropped from the mold.

[303Guy]

I've used as little as 3gr Clays to drive boolits through the bore 170 up to 198 gr if I remember. The bore tends to get rather sooty. 5gr of Clays gave good velocity (sub-sonic) and accuracy behind a 141 gr paper patched boolit. I'm only finding 4.4gr loads as a minimum in my notes but with 180gr to 194gr boolits. Those are slow enough anyway. I have used 5gr of Trail Boss which is quite light. Lighter than 5gr Clays.

[Larry Gibson]

What Jniedbalski said. Any cast .32 cast pistol bullet of .314 weighing 85 - 118 gr over 3.2 gr Bullseye [no wad or filler needed] will be less than shooting a 22LR in a light sporter.

Or as you surmise use your bullets and start with 5 gr Bullseye and work up to 8 gr. Should keep them below 1200 fps.

[MOC031]

Thanks all. It sounds like I'm in the right place to start, using 5 grains of the powders I mentioned having on hand as a starting point. I can move lighter than that, hopefully, depending on what the chronograph and targets tell me, in the time between now and when my brother gets here in a bit.

My guestimate is that if I can drop down from a starting point of 5 grains, get down to consistent velocities around 600 fps with these bullets, that would be a reliable load I wouldn't have to worry about sticking a bullet in the barrel, and hopefully accurate on paper as well.

The pistol bullet approach would be a no brainer, given the much lighter weight, but I don't have any jacketed bullets of that caliber on hand, and THE sporting goods store that serves the area doesn't have anything like that in stock. I can order some up, but they won't get here in time.

We will see how his neck responds to these light little loads. If they're both physically tolerable and he finds them enjoyable, then we can move on to his 25/06, 30/06, .308 Norma Magnum, and .338 Winchester if he's interested. I'll confess that if I were in his shoes and hunting loads out of my elk and moose hunting rifles was a door permanently closed to me, I'm not sure I would have any much interest in using those same hunting rifles to poke holes in paper at 50/100 yards would be all that appealing. It's a rough go for my little brother for sure; he's not even 60 years old quite yet, and his retirement plan was more big game hunting, not no big game hunting.

As for the chiropractor suggestion, this is a trauma injury to his cervical spine, not something that can be mitigated or corrected by manipulation. His last trip to the specialist, they were using imaging equipment to push needles from the anterior aspects of his neck to the proximity to nerve networks and then heating the end of the needle to specific temperatures to kill/deaden the nerve for a while at least. He said the doc said hopefully pain would be minimalized for at least six months, maybe more. The bright side of all of this is he's still walking around and living a normal life other than issues with what kind of movement his neck will tolerate i.e. recoil from firearms or shock transmitted through his arms from firing a bow. The things we never think are connected until we find they are... Far, far better for example than a diagnosis of cancer or something similar, which far too many of us have had with our parents and siblings.

Anyways, thanks to those who shared their experiences going light and others who offered their suggestions. If I have the time, I'll post up the resulting velocities and target results should someone in future also end up deciding to go down this path and be looking for a starting point.

[Krag 1901]

Sell one of the Moose rifles for a good .22 LR and go to town. Maybe a .17 HMR?

[Hick]

I realize this is sort of off the topic of your request-- but if light loads don't do the job he should consider a lead sled. There are versions of the lead sled that have a bracket that the butt of the stock fits into-- absolutely no recoil to the shooter.

[Texas by God]

The Limbsaver slip on pad is amazing for this. I eased back to shooting medium rifles with light loads and the pad; after shoulder surgery once and after brain injury once. The lead sled is recoil free as stated above.

Like Larry said 5 to 8 gr. With heavier bullets. I used 5 to 8 gr bullseye with my Noe mold .314 129 gr ,it’s a real sharp point bullet, and lee .312 160 2 r and my Noe .314 202 gr . 6 to 7 gr seemed like a very good load at 100 yards.They where not gas checked. I left them off and lube was 45/45/10 white label or lee alox. I did shoot some at 8 to 9 gr but used a gas check and they also shot good. The only bad thing about this load I can think is you better load a lot because they are so fun that every body that shoots it says can I shoot one more.

[MOC031]

He's already got a pin driving Ruger 10/22 that possibly the only remaining original part is the receiver. And an Anschutz position rifle. I truthfully don't even know if he'll have any real interest in super light loads out of his existing centerfire rifles - the Lee Enfield was for Service Rifle competition, and I expect that is just as over as the moose and elk hunting.


I realize this is sort of off the topic of your request-- but if light loads don't do the job he should consider a lead sled. There are versions of the lead sled that have a bracket that the butt of the stock fits into-- absolutely no recoil to the shooter.

We already have one of those in the family - the middle brother suffered a pretty good shoulder separation at work and had to have orthoscopic surgery to put it back together. It's been gathering dust for years; I tried it once out of curiosity and it felt like snuggling up to a rebar jungle (this was the Caldwell version of those out there). I assume the two of them may have already talked about the lead sled, but shooting from a lead sled is a far cry from silhouette competition and service rifle, along with hunting elk and moose.

It's all worth a thought - as is asking him if he has the slightest interest in benchrest shooting; selling his hunting and fullbore rifles and using that money to have a benchrest outfit built.

[MOC031]

How will these loads effect cases stretching in the web area ?

Truth to be told, I never thought of it. Nor do I really care - if getting Len shooting again means short case life, I'd just keep buying cases as required.

Now that you have me thinking of it, my guess is going to be "what case stretching in the web area"? All my cases after purchase have a false shoulder formed at the point where the bolt closing on the case is a light crush fit. So from the first time they're fired, they're essentially headspacing on the false shoulder/shoulder. Reloading consists of a Lee Collet die for sizing until the case gets to the point the shoulder needs setting back a bit.

With doing that (the same procedure for all my loads, cast and jacketed, in Lee Enfield rifles), my presumption is that there isn't much free room for the cases to be stretching anywhere. Perhaps there are some surprises in store, but if I was forced to bet money, my bet would be that there won't be any unusual case stretching. If I encounter any, I'll post here to report it.

[MOC031]

Like Larry said 5 to 8 gr. With heavier bullets. I used 5 to 8 gr bullseye with my Noe mold .314 129 gr ,it’s a real sharp point bullet, and lee .312 160 2 r and my Noe .314 202 gr . 6 to 7 gr seemed like a very good load at 100 yards.They where not gas checked. I left them off and lube was 45/45/10 white label or lee alox. I did shoot some at 8 to 9 gr but used a gas check and they also shot good.

Both yourself and Larry's loads have confirmed to me my original guestimate of starting with 5 grains of the various powders I listed is a good place to start.

It gets a bit weird after that (I think). Most would then see how much more velocity they could get without losing accuracy, leading, having to start using gas checks, etc. I'm going to see how far I can download to reduce velocity (and therefore recoil) while maintaining acceptable accuracy. Now, if the 5 grain starting point is quite comfortable, then of course I can start loading up until we figure out where irritation to his neck injury begins, then step down and back a bit from that point.

To give an example of how much of a difference is possible, the Lee Enfield with a ball round has a recoil velocity of 9.91 fps and recoil energy of of 13.75 ft. lbs. Harris's "The Load" with this rifle would be roughly half of that: recoil velocity of 5.62 fps and recoil energy of 4.42 ft. lbs.

In contrast to those, if 5 grains of those fast powders is somewhere up around 1,000 fps (if not less), then recoil velocity is down to 3.1 fps and recoil energy is 1.34 ft. lbs. Not quite a .22 rimfire obviously, but getting there.

And if it works with the Lee Enfields, then it should certainly work with the rest of his rifles, except possibly the .338 Win Mag. But there are no doubt some short relatively light cast bullet moulds available for that as well.

I bought ones for my .303 , .308 , .30-06 and 7.62x54.

Your rifle loads can also be loaded the lighter pistol .32 caliber Boolits that makes a good Gallery load.

Where did you get the adapters? I've only seen them for 32 ACP. I'd love to find a 32 long adapter for all the milsurps I have.

[GhostHawk]

I have had very good luck with 3 to 4.6 grains of Red Dot under the Lee .314 90 gr truncated cone cast bullet. Size as needed to fit 30-30, etc. But for an Enfield .314 should be just right.

Feels and sounds a lot like a .22lr, but in a heavier rifle recoil is virtually non existent. With a long barrel there is no muzzle blast.
Powder has burned before the bullet is halfway down.

I use 2-3 light coats of Bens Liquid Lube, apply sparingly, just a light hint of brass color showing.
Set in front of a fan, and you can be loading them in half an hour.

In my .30-30 these shoot to the sights at 25 yards, same setting as full power loads at 100.

Good luck!

[Rich/WIS]

Not 303 but 30/40 Krag, 5 grs of Bullseye under any weight cast (122-173 gr) is subsonic and recoils if non-existent. In non rimmed cases such as 30/06 same load works but enlarge the flash holes to prevent the case from shortening. Rimmed cases headspace on the rim and case shortening is not an issue.

[racepres]

Sorry if this is too late... But

With the current state of price, vs availability of 22rf ammo. I need to keep my young Grandson shooting.. Reactive 22RF targets.. Welp. by Accident.. I have a 1916/m93 Mauser with a short 300 Savage barrel on it. Essentially useless, for me, and since I shoot 99% cast projectiles... this one is little used. Revelation!!! Prime and charge with 3.0 gr of Red Dot [still available at our Sporting goods stores at about $26 to $30, a pound, and cheaper as "Promo"] a then stick a 0 Buckshot Ball in the neck. Hint, if you seat with something "flat" like a 44 Mag seater stem, you can get very Consistent Loads. Dip the exposed ball end, in LLA, and have more fun than I have had, in a very long time!!! Best Part.. my particular buckshot weighs up at 43Grains...and out of My Mauser... achieves 1200 FPS even!!! Prints very nice Groups Indeed... a Plus!!!

Pretty much... 22RF NO?

Yes... Bigger Hole in Paper, and very satisfying "slap" on Steel

HTH someone... I am having a blast!!!!

FWIW
For some time after my Broken Body Episode, I had similar Issues... plus couldn't (still can't very well) put my head in the Position for Rifle Shooting... let alone handle Any recoil.
My solution.. Handguns... YMMV

[Outpost75]

Having fun with this thread. Some years ago Sportsman's Guide had .303 chamber adapters for .32 H&R Magnum or .32 S&W Long as well as for .32 ACP. I tried them briefly, but none were as accurate as light gallery handloads in .303 brass. I was most interested in a 100 and 200-yard load for offhand and rapid-fire practice and so favored the heavier bullets which fed well. Larry's suggestion to use .32 pistol bullets is absolutely most economical choice for short range shooting and the Hornady swaged lead bullets given a light overcoat of Lee Liquid Alox with a minimum charge of Bullseye, TiteGroup, etc. will shoot ragged hole groups at 50 ft. to 25 yards.

Lots of food for thought in the posted article. It really helped me when I was developing light loads for cf rifles.

Hope your brother gets better.

[iomskp]

Short explanation: my younger brother suffered a whiplash injury bad enough he was designated 100% disabled for work and sent into early retirement. Amongst the other stuff, his specialist told him his days of shooting his centerfire rifles are over. Even the hand shock from shooting his recurves aggravates the injury, but he built himself a 45 lb long bow for hunting and finds that tolerable. His rimfire rifles he can still shoot with no problems.

So... one of his rifles is a No. 4 Mk1 Lee Enfield I gave him a few decades ago. He's heading over here in a few days, and I want to put together a REALLY light load that he can try and see if he can shoot it without irritation. Something below "The Load" levels of velocity and resulting recoil. I'm hoping that something with a velocity of about 700 - 800 fps with either one of my 175/185 grain moulds will be something that doesn't aggravate his neck injury. At least that would allow him to shoot targets/gophers, etc out to hopefully 50 yards at least.

I'm thinking/guessing of starting with 5 grains of Bullseye, W231, Clays, 700-X, Red Dot, Unique, C-300 (some of what I have on hand) to see how that goes and what the chronograph tells me. I'll be checking the bore after every shot for a bit to ensure I haven't stuck a bullet in the bore before the next round goes in the chamber.

Before I start assembling loads... anybody out there who's already done something similar in .303 British with similar weights of cast bullets? How did it go and what kind of velocities and accuracy did you get?

My reply has nothing to do with loads, I was involved in a 100 kilm head on and suffered whiplash and spinal fractures and was left unable to shoot my 12 bore rifles or even my 300 H & H, what works for me at the range is shooting off a standing bench that way I don't support the full weight of the rifle and I can roll with the recoil, I hope this helps him

Here are some other ideas for gallery loads.

[303Guy]

I have recently played some with light loads in my Lee Enfield (sporterized) and I can say it's more fun than full power loads. Even lighter 'full power' loads are more fun. My first attempts were not accurate enough to satisfy me although I'm seeing hunters sighting in their rifles with less accuracy and precision, saying it's good enough for deer. I won't be hunting deer - my quarry is smaller and requires minute of beer can at 100 yds but does not require full power 303 loads, although they do work. One can imagine what a 180gr bullet does to a turkey! I just don't need the muzzle blast and the recoil. Admittedly, being able to nail 'em out to 200 yds is great but I don't expect anything further than 100 yds. Besides, most of my 'hunting' will be at the range shooting holes in paper. That's when low to no recoil really shines! But at the moment I'm still having fun with 22's.

My light load powder of choice is Trail Boss but so far have not had the greatest success but then I haven't given it a fair trial yet. 5 gr of Clays has work in the past so I'll be trialling that powder alongside the Trail Boss. The great thing about Trail Boss is that it fills the case or close enough.

[MOC031]

Thanks for all the ongoing suggestions, etc. Had a couple of days of really fun weather here since winter decided it forgot something on it's way out and came back. Not much time for 'puters or the reloading bench. I will get around to posting up some replies.

On the other hand, helping a ski patrol buddy yesterday, he said his brother had some shooting stuff that he left behind when he moved, and maybe I might have a use for it...

That mold should give you some decent plinkers to try with the .303B. At least to let you know if you are going the right way.

[3006guns]

Well, all I can contribute is a anecdote........

Many moons ago I move to Oregon and hauled my very nice '03 with me. When I bought it at a gun show, the seller threw in a bandoleer of armor piercing 30-06. As a result, I thought ALL .30 caliber rifles kicked the snot out of you. A gentleman I met in Oregon gave me a handful of his "pipsqueak" loads, consisting of a .32 caliber pistol bullet over a small charge of shotgun powder. I didn't have the sense to ask about the powder or charge weight unfortunately.

To my absolute delight, the rifle had NO recoil at all and hit dead center using the battle sight at 75 yards. Since the battle sight is set at 575 yards (I believe) there's no fiddling with elevation. So, the advice to use a .32 bullet of perhaps 100-115 grains (like a 32-20 bullet) and small charge of fast powder is good. Try it and you'll like it!

[Texas by God]

I tried the Lee 314TLswc over 4.7grs(.5cc) of Bullseye today. It shot well for me offhand at about 25 feet. No hearing protection or recoil pad needed. Single shot only due to short OAL. https://uploads.tapatalk-cdn.com/20210426/6943db54544d585eb11b756b1335c85a.jpg

I´ve used 5 to 6 grains of HP 38 with different boolits ranging from 160 to 180 gns. Mostly Lee moulds.

Tumble lubed with LLA or BLL´s, no gas check, soft alloy. In my N4 MkII they will clock somewhere between 1000 to 1200 fps,
giving me pie plate accuracy at 150 meters with original iron sights.

I don´t feel confortable using such small volume loads in a rifle cartridge case with lots of empty room inside so I always use a filler with those loads, 0.5 to 1.0 grains of kapok over the powder charge. Besides, they tend to ignite more consistently when using a filler IMHO.

For shorter distances like 50 yards or so, .32 S&W Long boolits around 100 grains will group nicely when shooting from a bench.

Recoil is almost non existent with any of those loads. And they are fun to shoot too. I enjoy them much more than full rifle loads.

Argie.

[303Guy]

I like a filler or positioner myself. Beware of cotton wool. While it makes a wonderful filler, it can also ignite and smolder. Not always though. I did experiments with it and takes specific conditions to ignite but when it does it can set the countryside on fire. Kapok apparently not although I have not tried it. I use Dacron.

I've tried 32 100gr boolits but I think I was driving them too fast. I still have a few actually. But for the length I lean toward heavier boolits to reduce boolit jump. I want the ogive to actually contact the throat. I haven't tested the differences so I can't say what's best. But, I do have a few boolits to test and will be doing so soon enough. My load will be 5gr Clays under 130gr Mihecs. I have what I have decided to be a dedicated cast boolit rifle. In fact, I might even load up a few this afternoon to test on Sunday.

MOCO31 you sound like a good brother. My brother called me the other day and said he had a saw for me. An almost new porter cable 315-1 I have worn out 2 sets of bearings in my old one I retired a few years back, and my 356 is shot also. I really liked the original 315, they were like chrome when they came out of the box.

Brazo Precision has some 120 gr 32-20 boolets BB for a good price ($49 for ~850ea delivered), powder coated I just ordered. they come in several dia (.312-~314") Might fit a .303? I'll be using them for .308 & .30-40 K.

[15meter]

Round ball loads were some of my first rifle loads. 308 that had been converted from some kind of mauser.

Think I paid $39 for the rifle.

I got the recipe out of a book I checked out of the local library, went back a number of years later to reread it and it was gone. We had a new library director that pencil whipped virtually all shooting/loading/hunting books out of inventory.

but he did have a whole stack of Madonna's book from a couple of decades ago.

He laughed in my face when I questioned getting rid of the hunting/shooting stuff. And this is a reasonably rural county, I got the impression that he was going to re-educate us.

He didn't last long before he went on to greener pastures, may have had something with his contract not being renewed.

But round ball loads are still worth the time for executing tin cans and other politically incorrect behavior.

[Alferd Packer]

I think that starting with close range 25 yard loads and then getting them to shoot from one inch loads to all thru the same hole would tech you what shooting and reloading cast bullets is about. The reloading seems to be the same, but shooting cast is a whole new ball game. What works for jacketed bullets is not the same.
I have seen first time shooters get excellent groups, but they are usually being coached by an experienced cast boolit shooter, or sometimes they have done a lot of homework on the subjectb

[Alferd Packer]

You should slug the bore of that milsurp first thing.
Barring that, I would get some cast bullets about.314 diameter and load 3 or 4 grains of Bullseye,700x or Red Dot or a fast similar powder and shoot at 20 to 25 yard targets and practice to shoot the smallest group.
This will give you a feel for how the gun shoots cast bullets and give you more confidence in the gun.
Stay away from 100 yard shooting for now.
These slow bullets taking their time to wander down the bore take quite a steadg hold for100 yard shooting.
Learning to hold steady at close range and shoot them all thru the same hole or a one inch hole can reach you to hold steady for those 100 yard shots.
A two inch group at 100 yards rather than an 8 inch group all over the target.
Lead .32 pistol bullets work real well for .303 Brits.

[Alferd Packer]

Where did you get the adapters? I've only seen them for 32 ACP. Ij'd love to find a 32 long adapter for all the milsurps I have.
I recommend adaptors only for rifles that shoot rimmed cartridges. .303 Brit, 7.62×54 Russian and .30/30 win and .32 Special.
They won't jam in the chamber.
The 06 and .308 can get stuck.
Requiring A gunsmith to remove.
Just from my experience.
Better to load your own. reduced load for 06 and .3.08

[Wild Bill 7]

I watched a video of a man (don’t remember his name) that used a lead sled to capture the recoil on his rifle. I also believe it was a 303. Anyway he had broke his collarbone and needed help with recoil. The video was him shooting for a world record. Don’t remember all the details except him using the lead sled. Maybe someone knows more about him as I only saw the video once.

I believe that is Ernest Jimenez

I think I got my chamber adapters from both Sportsman Guide and one from Gun Parts Corp.
So far they have worked fine , even in my .308 and 30-06.
I have never had one get stuck in the chamber.
But then I do all my own gunsmithing.
So if they do get stuck , it won't be hard for me to remove the adapter.
