Lyman 311410

[rmcc]

Hi all,

Does anybody have any load data for this mold? As near as I can tell, it was offered in the late 40's. It casts a 125-130 gr.

I plan on using it in a 30/30 for plinking. I have come up with about 13 gr Unique or 16 gr IMR 4227 or 2400.

Thanks,
Rich

Rich,

That's a flat based round or semi-pointed boolit, that works welll in the 30 carbine. I'd be careful loading that in a 30-30 assuming you have a tube feed magazine.

You're in uncharted territory. Be careful. Test at your own peril.

I hope this helps,

311410 is a plain based round nose design. In my Lyman cast manual it lists it for light loads in 30 cal. rifles, but no load data. After reading some other posts, I think I will back off the load of Unique to 10 grs. Where do you get dacron filler? Or can you use corn meal?

Thanks,
rich

I have that bullet in a Lyman HP single cavity as a BB. I had Hollow Point Molds (Erik) remove the BB and make a new spud. The original Lyman pin was so long it went 3/4 of the way through the bullet. I liked it so much in my so Carbine BH I got two 4 cavity brass molds from MP, one PB and one GC. I haven't yet done anything with the gas check mold though it was intended for the 30-30 so I haven't any data for that yet. I would suggest SR 4759 for this bullet in the 30-30 starting around 16.0 gr. RCBS 150 gr at 19.0 gr gives me 2150 out of my 26 inch barrel.

Hope this helps some.

That boolit shoots well in my Mossberg 30/30 at an MV of about 1250 fps. I keeps the gong swinging at 150 yards with open sights. I am using 5744 powder but don't have access to the charge at the moment. No filler is needed and the lube is Lee mule snot.

[cbrick]

4759 and 5744 are about the same burn rate and 4759 may be unobtanium by now. Would be interested in learning your charge and if you you've tried stepping it up any?

I just found my notes. 14 gr of 5744 gave an MV of 1365 fps. according to my chronograph. I also tried Trail Boss using the 1.9 cc Lee dipper (don't know the charge) and I got 1250 fps. No leading on either load. I created both loads for a very low recoil load to be used with new shooters. That boolit also shot passably well in my 308 but I only loaded a handful of those out of curiosity generally preferring GC'd 160's for it at higher velocities. In the Mossberg lever, I have only been loading them single shot but my RCBS Cowboy Seater die puts a significant meplat on the nose so I would not hesitate to use them in the magazine if the need arose.

I've had good results with the Mihec 316410 in my .303's using IMR 4227 at around 22 grs. .303 British has more volume than .30-30 so your 16 gr. suggestion should be in the ball park.

Have you looked in the Lyman Cast Bullet handbook? There are lots of .30-30 loads but I can't recall if there are boolit weights of around 130 gr. If you don't have the book I will look up some loads for you.

So far I have only shot the deep HP and it is explosive! A stock Lyman mould is a solid though so you would not experience that. I do like my Mihec mould. However, I have shot anymore since last summer.

Well, not a lot of help as my Lyman Cast Bullet Handbook third edition does not list IMR4227 or 130 gr. boolits. However, the Lyman Reloading Handbook #44 here:

http://castpics.net/dpl/index.php/reloaders-reference/reloading-manuals/191-lyman-manual-44

has a section on cast boolits and lists the 311410 with a variety of powders including Unique and IMR4227. The max. load for Unique listed is 12 grs. though so you might want to back down some then work up if you use Unique.

That's about the best I've got to offer except that I really like that boolit (Mihec version) in my .303's ~ light recoiling, cheap on lead and seemingly accurate.

I looked at my notes for that boolet in a Model 94 and here are the results:

311410 sized .310."
FC cases, light crimp, OAL 2.573"
Rem 9 1/2 LR
6.0 grains Bullseye
Av. 1295 fps, Es 10, Sd 3.2

Accuracy was only 4" 10 shot group at 50 yards. Just a little disappointing from a carbine that will generally hold groups much tighter than that with the 311041 170 grain boolit. I've not played with the 311410 over any other powders other than Bullseye.

While the accuracy in my Model 94 was not worth a hoot, it shoots very well in my K31 Swiss rifle and holds almost 2 MOA out its barrel.

way before the Rick’s MP group buy, I had found a single cavity 311410 mould that had the bevel base removed.

I have a H&R 30-30 with 22" barrel that I shoot a few of these boolits for plinkin

LP primers, 7½ grains Unique, and the boolit cast from 50:50 (ww/pb) alloy gives a velocity of about 1450 fps

ole Junior always taught plain base boolits start to lead long about 1500+ fps and that has been my experience too

RMCC,

Here is a good Dacron thread:

I hope this helps,

We shot gobs of them thru 2 Win 94s in the mid 70s. Load was 10 gr Herco with no filler and they shot pretty well. No groups that I remember, we shot cans,rocks,blackbirds........
Never had any issues with the magazine and we filled them up. Wheelweights and sized thru a 310 push thru , finger lubed with some red water pump greese.
Now I'm going to have to put some handles on that mold and cast some, brings back good memories.

Where do you get dacron filler? Or can you use corn meal?

One big difference with corn meal is that it reduces your effective chamber volume. Dacron filler is fluffy, and mostly air. Corn meal actually takes up space, leaving less room for the powder gasses to expand, which means higher pressure.

I once managed to get a flat primer and sticky extraction using only 12 grains of Unique, in .303 British, with a 311410, by filling up the rest of the case with grits. A learning moment -- one hopes. :-)

I would still use grits or corn meal, in certain ways. But slowly, and carefully.
