Super Heavies in the 357 Max

[curioushooter]

Does anyone have any experience with slower powders, like from AA1680 to H4895, using heavy bullets, from 200-300 grains in the 357 Max?

In particular I am looking for a start load for a 230 grain cast boolit in a T/C G2 Contender. There is AA1680 data out there from Western up to 200 grains, but nothing beyond. Would quickload work for guesstimating this?

In fact, even 357 Mag data with these super heavy for caliber bullets might be useful.

Thanks!

[Hamish]

I see that the '2000 edition, yellow front T/C load book shows 18-20 of 1680 at 1450-1650fps for a 210gr FNGC. Surely you could start at 17gr.

Only caveat I see is 1680 produces quite a bit more pressure than 2230 and markedly more than 2015. Unsure where 2400 falls as far as pressure.

[Moleman-]

I saw your post in the lilgun thread. While I have 1680 I don't use it in 357Max, but I do have a NOE 360-228FN mold that I shoot in it. What is your COL for that NOE 360-230RF?

[curioushooter]

Hamish, the western powders load book has 200 grainers over 30 grains of AA1680 and it isn't even breaking 40k PSI. That's a 15% increase in bullet weight. Drop the charge 20% and you have 24 grains maximum charge. Drop it 30% and were at 21. Is that T/C book really conservative?

Moleman, I don't have a NOE360-230RF. COL, however, is somewhat arbitrary in a Contender with a throat like the one I have. What do you use for your 360-228? I mean, I am not married to 1680. I just have it and it seems to be about the right burn rate for the application. I have some IMR3031...that seems too slow. I have some IMR-4198, which is close to 1680 but lacks it's density. I also have Win296/Lil'Gun/AA#9/2400...I think those are really too fast for bullets this heavy for caliber. Lil'Gun is very impressive with 180s. And it is the slowest of that bunch. 1680 is like it, but slower...and denser.

I have some rye and winter wheat growing, too, Moleman! The weather here has been sunny and about 45 degrees...you can see the Rye growing. Our Gray Dogwoods are coming into bud! Last year this time it was -6!

[Moleman-]

Was out walking in a winter wheat field yesterday with the Mrs. Was only up about an inch to inch and a half and we've had a mild winter. Had to hose mud off of my boots when I got home. Saw deer, turkey, squirrels and one fox.

So far I've only shot the 228gr with Lilgun and W296 (and a few with W231 trying for a subsonic loading in my 9" pistol with a shorter freebore). Except for the pistol I've been using a COL of 2.100" with that bullet. I need to start casting again as I'm out of the NOE228's and down to less than 20 or so of the 208grWFN. I've been reluctant to try AA1680 as going by quickload data it can't touch what I'm getting with W296 and LilGun according to the magnetospeed. It could be a case where QL is wrong, but it's been pretty close so far with W296, 2400, LilGun and IMR4227.

[curioushooter]

Well, I could be wrong. I don't have quickload. I am basically interoploating from 375 Winchester. The cases are the same shape, same peak pressure (well, in a G2). Matching a 250 grain .375 sectional density to a .358 leaves one with 228 grains. So reducing the .375 max charge purpotionate with reduction in case volume shoukd leave me with a max load of 1680. G2s are strong...in fact I shot mine with 375 Winchester and found it excessive and wasteful..even with a 15" barrel on it. Trying basically to get 44 mag performance from the max.

[Moleman-]

Haven't ran these over the magnetospeed on the pistol, but average on a 15.5" barrel with the 360-228gr NOE FN 2.100 col, LilGun 1748-1800 fps at 49-57Kpsi.
W296 was close at 48-57Kpsi, 1750-1830 fps. QL says you'd lose around 160-170fps with the 9" barrel on the top loads. This is why I'm reluctant to try 1680- 21.0gr AA1680 everything else the same with a 16" barrel QL shows 1672FPS, 46,720 PSI, 89.96% burn. 9" pistol would come in at 1544fps.

In a strong action, there is no reason they can't be loaded up to 223 pressures.

[Hamish]

Curious,

Interesting that there is so much difference in the data, but yes, the '2000 data seems pretty conservative. Personally, I find the recoil pulse of 110/296 a little obnoxious so have been using 2400.

Former CB member 357Maximum is a huge proponent of 300MP in the Max. At the point I start getting serious about switching from the Mag to the Max to hunt with in the Contender I will be switching to 300MP.

[Meatpuppet]

Super Heavy in the 357 Max:

357 Max / 300gr Swaged Coated Lead S6 Ogive / Projectile 1.258oal / VV N350 - 8.0gr / CCI SRP / Cartridge 2.3oal / 16" barrel / 1062fps

Super quiet with a suppressor. Soft swaged lead expands on impact.

[curioushooter]

Western Powders got back to me...a 215 cast boolit with a 23 grain max load with AA1680. I assume a contender only affair...
I really should but some 300-MP, too.

[Moleman-]

My 208gr RCBS cast come in around 215 lubed with a gas check. 2.140" Col, 23.0gr AA1680 , 33.6gr water capacity case, 40Kpsi, 1741fps QL guestimate out of a 16" barrel 1576fps out of a 10" barrel. The stickler is going to be seating depth, 2.100" brings the PSI up to 45K, 2.050" brings it up to 52K. Again, they're just guesstimates but it has me curious as guys generally speak so highly about 1680 in 357Max and it doesn't look like the speed is there compared to faster powders. The last update I got from QL didn't have 300MP listed as I'm curious about it also.

[Good Cheer]

Just a passing thought to throw out there.
In a single shot isn't it worth while to get a bore rider design that minimizes the amount of case volume taken up by lead?

[curioushooter]

Yea...bore riders are the mainstay. Also, because contender handguns are not so long of barrels, you generally don't run out of lube.
I am aware of a load using H4895 and that massive 288 grain Lyman 358 borerider bullet. There is also that 200 grain Lyman borerider. Don't have that mold and my boolit mentor hates bore riders so I can't borrow it. Maybe I should check western bullet company.

[Good Cheer]

You could always design what you want and consult with a couple few mold makers to see if adding it to the line up would be smiled upon.
That was the path I followed for the .45 Colt single shot.

[curioushooter]

Not a bad idea.

[hc18flyer]

I am following this thread for my 357 max. I have the RCBS 35-200 and the NOE 35-230 molds. Would like to use the 230 for hunting, if I can find a safe load in my Henry single shot? Please post your findings. Thanks, hc18flyer

[MT Gianni]

I would work up from starting loads for the Ly358627 which in my alloys have always run closer to 226-228 gr than 215.

[curioushooter]

Another idea I had in the super heavy range is the lyman 280 grain bore rider. Wonder what that would do with a slower powder; if that could do 1400 you'd have a formidable penetrator and with soft alloy could expect some expansion.

[Moleman-]

I am following this thread for my 357 max. I have the RCBS 35-200 and the NOE 35-230 molds. Would like to use the 230 for hunting, if I can find a safe load in my Henry single shot? Please post your findings. Thanks, hc18flyer

Not familiar with the Henry single shots. Do the 357mag guns use the same receiver as their 223?

[cwlongshot]

Ooh boy!! What a bullet!

I have a 230 Keith bullet I have shot in mine good shooter. Id need to check my notes to remember loading.

Never even considered trying that NOE 280!! For me that Whelen and Norma Mag fodder!

[hc18flyer]

Not familiar with the Henry single shots. Do the 357mag guns use the same receiver as their 223?

Yes, available in .357 magnum. Having Mike Bellm open it up to Max. I am looking for specifics to start developing some loads. Picked up some IMR 2442 and brass.
hc18flyer

[Moleman-]

hc18flyer, how long is Bellm making the freebore and what are you going to use as your max chamber pressure? Is that IMR 4227? I have the RCBS 35-200 and the NOE 360-228 molds although I've not used IMR4227 with them. Once you get your barrel back figure out a basic COL and I'll run it through QL with IMR4227.

[hc18flyer]

GREAT, THANKS! Yes it is IMR 4227. I think the Henry will handle 50,000, I'm not looking to max the max, just a nice 'plate smacking load', and a hunting load for the NOE 35-230. Tom

[Texas by God]

CW thanks for those pics!

[curioushooter]

AA2015? Interesting. Slower than 1680 but not as dense.

[KLR]

I'm in. I just finished putting together a 357 Max and would like to find a good deer load for under 150 yards. I have the NOE RD 35-230gr mold. I had the RCBS 35-200 NOE mold but sold it. However, I still have a few bullets.

Today I loaded one round with:
35-200 bullet. Mine weighed 216gr
17gr of Lil' Gun
OAL of 2.160.

I shot it over the chrono and the velocity was 1760 fps.

Moleman - Would you be willing to run this through Quickload and see how much pressure it was?

BTW, the 230 gr bullet will have to be seated a lot deeper in my rifle due to the large nose. Or sized down.

[Moleman-]

KLR, the 216gr bullets you sent me is what motivated me to finally get a lubrisizer. I used the RCBS 35-208 as a basis but changed the weight to 216gr and the length to .886" (measured one of yours). 2.160" COL, 17.0gr Lilgun, standard 33.6gr water capacity case, QL guess is 26,203 PSI, 20" barrel 1665 fps, 24" barrel 1716 fps. Ran it the first time and it came back slower, so went out to my bullet stash and found one of yours, measured it and adjusted the QL. Still coming in a little slow unless you have a 26" barrel.

I was running them around 1830 fps out of a 16" with W296 which puts a good thump on the steel plates at 150yds, but so far haven't taken a deer with them. I have the Lee copy of it now.

[KLR]

Thanks, Moleman! My barrel is 18.5" Maybe my chrono is off? I only shot one and it was the first bullet out of a freshly cleaned/oiled barrel so maybe that did it? Anyway, I loaded four more tonight and will shoot a group and chrono all four shots.

I played around with the 230 gr RD bullet and it will have to be seated deeply in my rifle, or I'll have to size down that fat nose. I think I'll just get the Lee copy of RCBS bullet and modify the mold to make the meplat bigger by cutting the nose length back.

Edit: In a PM with hc18flyer he mentioned using 360 DW brass with the 230gr bullet. So I took a piece of 357 mag brass and seated the bullet until it just fit in my chamber. Results were a 2.010" OAL. The bullet is .910" long. Would you be willing to run this in Quickload for me? I have Lil' Gun, 300-MP, 1680, 110, 2400.

[KLR]

I shot four more of the 35-200 clone over the chrono today. Results were 1716, 1707, 1745, 1731. Average 1724 fps. They went into a .72" group at 60 yards.

[Moleman-]

Nice!

[KLR]

Today I loaded a 230gr bullet (sized to .358) over 6gr of Titegroup. I used 357 Mag brass and seated the bullet to an OAL of 2.0" Velocity was 1050 fps.

https://photos.smugmug.com/photos/i-3Hw6mNW/0/f5684d19/M/i-3Hw6mNW-M.jpg (https://www.smugmug.com/gallery/n-ddVKkb/i-3Hw6mNW/A)

It wasn't fast enough to stabilize in my barrel. Four rounds went into 3.5" at 60 yds and lube smears on the target bullet holes were uneven.

I cast some more today (plain base and gas check) and will PC the plain base ones and up the velocity.

Probably switch to Lil' Gun too, but not sure where to start. Maybe 12-13 grains?

[Moleman-]

If that's the NOE 360-230FN then QL is pretty close at 1070 for the guess from COL 2.0, 6.0gr titegroup. 12.0gr LilGun guess is 1226 fps, 13.0gr is 1325 fps, 15.5gr is 1558 fps at 32Kpsi....ISH.

[nagantguy]

Great great info keep it coming please I’ve kinda just started down the heavy 357 max road myself, seeing what authority a 218 grained pcd and CG’d put on large MI corn field does! 180 or so seems the sweet spot with Jwords but like the Dr.’Suese book on beyond zebra; some people stop there but not me, if 200 was really good and 215 was awesome and no pressure signs , and I’m eagerly awaiting my 360-200 MP hp group buy mold! High 190s or low 200ish hps should be great deer big bear medicine!

[KLR]

If that's the NOE 360-230FN then QL is pretty close at 1070 for the guess from COL 2.0, 6.0gr titegroup. 12.0gr LilGun guess is 1226 fps, 13.0gr is 1325 fps, 15.5gr is 1558 fps at 32Kpsi....ISH.

Thanks! That is a NOE 360-230FN. 32Kpsi doesn't sound too bad, but I really don't want to go much higher in my converted shotgun. I think I'll start at 14 grs and see how it shoots. Likely I'll go with a modified 35-200 for a hunting bullet.

[Stephen Cohen]

KLR that is one hell of a nice bullet, This is an interesting thread as I also have a 357 max on a Martini action and just love it. Regards Stephen

[hc18flyer]

My Henry will be in next week and I can figure out my col, so Moleman can run some loads thru QL for me? KLR- Happy to send some 35-300 gc for you? I like the NOE 35-230fn, that big meplate makes for a distinct 'thwack' on a whitetail! Hope to get caught up reloading other stuff tomorrow, cold and snowy outside! hc18flyer

[hc18flyer]

Sorry- RCBS 35-200 gc boolets

[KLR]

Sorry- RCBS 35-200 gc boolets

hc18flyer- Thanks for the offer, but I still have a couple hundred of those 35-200 bullets that I cast before I sold my mold. I'm thinking about making a jig and milling off the nose to make a meplat as big as the 35-230 bullets. If those work well, I'll order the lee mold and modify it. Like this:

https://photos.smugmug.com/photos/i-K6v8R7z/0/74f65f4a/M/i-K6v8R7z-M.jpg (https://www.smugmug.com/gallery/n-ddVKkb/i-K6v8R7z/A)

It looks crude, but casts nice bullets. I have a milling machine now so I'll be able to do a better job.

Anyway, I got my first order of powder coating yesterday and will try powder coating. How's that for adding another variable into the mix? Lol.

Stephen - That bullet is a Ranch Dog design. He originally made it with tumble lube grooves and in 30 cal. NOE sized it up to .360 and changed to normal grooves.

[McFred]

Hey guys, just in case people hadn't thought of it yet, Hodgdon CFE Black is a similar speed as lilgun, and 1680. Might fill the niche in terms of density and burn rate.

[Moleman-]

I've also been looking at the MP-359 220gr WNFP HP GC, or perhaps having it made a little heavier near 260gr. For my rimless the Lyman 204gr RN looks good too. I need to start casting again before it warms up and I've got nothing to shoot.

[KLR]

I need to start casting again before it warms up and I've got nothing to shoot.

Not only that, but Winchester is counting on you to develop their new heavy bullet hunting load.......;-)

[Moleman-]

I saw this pic leaked online. Looks like they went with someone elses design this time :-D

[KLR]

I saw this pic leaked online. Looks like they went with someone elses design this time :-D

Ahh, yes. The Extreme Penetration Projectile. I heard that they gave up on that due to poor accuracy. :lol:

Anyway, today I put a few 35-200 bullets in my milling machine and made the meplat about .280". As pictured, original bullet weighs 219.5gr and milled bullet is 210.0gr. I'm going to load them with 17gr of Lil'Gun and see how they compare. It's windy with gusts to 50 mph, so I won't be able to shoot today.

[Moleman-]

We're getting the same storm. Has to be pretty windy for snow to blow into my barn from under the overhang, but it'd currently snowing on my Sheldon lathe :( Got a tarp on it now and the diesel generator on the charger waiting for the power to go out.

[KLR]

It's just wind here, but I've had a few shingles blow off my house. Guess I'll work on that tomorrow...

[rockrat]

Will have to try the Hodgdon "BLK" powder as I use 680 with the 35-200 (mine comes close to 220gr) for around 2000fps. 2400 works better with the same boolit @2300fps. Heaviest boolit I have used is the 260gr "hammer", over 680, for 1930fps

[Meatpuppet]

How heavy do you want to go? Left to right were all swaged in BT Snipers Dies:
240gr Swaged from 9mm Brass
260gr Swaged from 9mm Magnum Brass
280gr Swaged and Powdercoated (Smokes John Deere Green)
290gr Swaged and Powdercoated (Smokes Clear)
310gr Swaged and Powdercoated (Smokes John Deere Green)
310gr Swaged and Powdercoated (Smokes John Deere Green)

I shoot them through 357 Maximum 1-10 twist MGM barrels. 10" barrel for suppressed and 16" barrel for velocity. I found the faster twist is necessary with the heavier boolits.

236770

236771

237121
Edited to add 300gr 357 Maximum loaded long. 38 Special next to them for comparison.

[KLR]

I loaded and shot three of the 230gr bullets today. I powder coated them and seated them in 357 Max brass. I loaded them with 16.5 grs of Lil'gun and a CCI small rifle primer. I intended to use the 15.5 gr load that Moleman ran for this bullet, but instead of checking this thread, I was sure that I was remembering correctly and loaded up 16.5 grains. Shame on me for not double checking.:shock:

https://photos.smugmug.com/photos/i-RXdKHjD/0/aafae0b5/M/i-RXdKHjD-M.jpg (https://www.smugmug.com/gallery/n-ddVKkb/i-RXdKHjD/A)

Anyway, nothing bad happened, primers looked fine, and it put three into 1.4" at 100 yards. For my converted shotgun I think I'm pushing my luck and have decided to dial it back to milder loads and lighter bullets.

Maybe some of you with a strong rifle might find this useful.

Moleman - Would you be willing to run this through Quickload with 16.5 gr of Lil'Gun? Thanks.

https://photos.smugmug.com/photos/i-6j9j8mV/0/f509c563/M/i-6j9j8mV-M.jpg (https://www.smugmug.com/gallery/n-ddVKkb/i-6j9j8mV/A)

[Moleman-]

KLR, are you using the same 2.0" col or 2.1"? I ran it both ways.

2.0" col, 360-230fn NOE, 16.5gr Lilgun 18" barrel....39,116 psi, 1640 fps.

2.1" col """"""""""""""""""""""""""""""""""""""""""""".....30,293 psi, 1579 fps.

Ran the same with 2400,

2.0" col, 13.0gr...35,868 psi, 1507 fps

2.1", col 14.0gr....35,081 psi, 1546 fps.

Are you using a SB1 frame with the large firing pin or some other type of single shot shotgun? I've got a very old eastern arms 12ga that I've thought about making a 357Max on after putting a smaller dia niedner type firing pin in it. I'd have to make or find a new stock is the only thing holding stopping me.

[KLR]

Moleman - Thanks! I'm using a 2.0" col. I'm using a Pardus (Turkish Folder) 12 ga shotgun. Here is my build thread:

http://castboolits.gunloads.com/showthread.php?375340-Converting-Pardus-(Turkish-Folder)-12-ga-to-357-Mag

The problem I'm running into is that the hammer just isn't hitting hard enough to set off rifle primers consistently. Increasing the hammer spring strength increases trigger pull too so I'm going to have to be happy with pistol loads.

[cwlongshot]

Try a Federal Primer. They are softer.

If using a SRMag or Match primer switch to and try a std SR primer.

CW

[KLR]

I'm using a CCI 400 SR. If my latest "fix" doesn't work I'll find some of those Federals.

[KLR]

2.0" col, 360-230fn NOE, 16.5gr Lilgun 18" barrel....39,116 psi, 1640 fps.



I had one of these rounds left and just now shot it over the chrono. It was 1664 fps. 18.5" barrel.

[Moleman-]

That's pretty close. If you figure if there's no free lunch, you can adjust the case water capacity to 33.0gr so the FPS matches the chrony which bumps your pressure up to about 42,126 psi. The bolt thrust is less than a 12ga and you've put a smaller dia firing pin in it. I wouldn't go higher though on the outside change you pierce a primer.

[KLR]

Thanks for running that. Sounds like I'm at the upper limit of a safe load. I'm going to go back down to a lighter bullet and lower pressure since I'm dealing with an unknown Turkish shotgun.

But those with a strong rifle might find this info useful. I'll bet that 230gr bullet would be a good deer bullet at any distance you could hit it with.

[hc18flyer]

hc18flyer, how long is Bellm making the freebore and what are you going to use as your max chamber pressure? Is that IMR 4227? I have the RCBS 35-200 and the NOE 360-228 molds although I've not used IMR4227 with them. Once you get your barrel back figure out a basic COL and I'll run it through QL with IMR4227.

Moleman- I finally got around to getting my info together for the NOE 35-230 rf in my Henry 357 Max. :Starline Max brass, 1.595 length/ NOE bullet .910 long, sized .357/ 2.220 coal. Henry uses one receiver for their rifles, including .223 and .308. I have both IMR 4227 and Accurate 1680, leaning toward the 1680. Thinking 20 or 21 grains? Not sure where to start on the 4227? Thanks, hc18flyer

Sorry, bullet weights 235 grains in my soft hunting alloy of 2/3 coww, 1/3 soww. I do have a Forster hollow pointer for my case trimmer, considering lightening them up a little?

[Moleman-]

Ran IMR 4227 and the 1680 using the NOE bullet 2.22" COL and a water capacity of 33.6gr didn't change the bullet weight from 232 to 235 as it only makes a few fps change in the QL guestimate and a 16" barrel.

21.0gr 40K 1690fps
20.0gr 34.8K 1618fps
19.0gr 85% density 30K 1544fps

1680 25.0gr 99% density 49.8K 1815fps
24.0gr 43K 1741fps
23.0gr 37K 1668fps
22.0gr 87% density 32K 1595fps

*** I haven't loaded very many 357Max with 1680, but have run numbers for others who all have reported similar results. For some reason the QL software doesn't do a good job guessing the speed or pressure at least in 357 straight walled cases 1.6" to 1.8" long. Often giving very high pressure and lower fps guesses. You should always work your loads up, but keep this in mind when using 1680***

Thank you!! Happy to start at 22 grains of Accurate 1680, and chrono as I go up. My 22" barrel should help a bit too. I would be 'tickled pink to get in the 1800 fps range, even 1700 with 1.5 moa accuracy. My Grandson and I have shot the Henry a bunch, but haven't run loads over the chrono yet. hc18flyer

I use 24.0gr of AA1680 and the Accurate 36-270 and the MP 220 FN (HP). I have yet to chrono the latter but the 270gr LFP chronos at 1755fps in my 22" barrel. Accuracy from both is stellar.

Thanks, Dinny

I shoot 357 Maximum in an H&R HandiRifle with a 1:14 twist that was rechambered from 357 Mag with a fairly long throat.

I have used up to 21.0 grs of H4227 for about 1800 fps, and 21.0 grs of IMR4198 for 1550 fps. Further work will employ more IMR4198, probably up to a full or near full case.
