Reloading 357 Mag with 200 gr Lead Bullets

This guy has info on 231 and 296 powders. Not exactly what you are looking for but info on 200g 357mag is pretty slim.

Going out to look for "Big foot", huh ?
Sorry I could not help myself.
4227 filled to maximum might be the way to go with that hunk of lead.......
There is a fine line between "Fast and "slow" type powders when you get into this range of bullets.
Gas checks also add to the pressure of the loads.
This load is out of a 6" tube or longer....right ?

From the 1996 Alliant manual(Because that is the one immediately at hand!) for 200 gr. LRN, probably Lyman 358430, 10.0 gr. 2400 at 32,800 psi and 1,245 FPS from a 5.6" test barrel. Alliant only lists maximum. Reduce it as much as 20% if you want.
I chronographed the 10 gr. 2400/358430 years ago in an 8 3/8" Model 27 but apparently didn't record it in my log. It wasn't too fast as I recall. Need to change the rear sight blade to get the sights to adjust to zero.

FYI, you will likely need a gas checked cast bullet with those powders to eliminate leading.
Hopefully not flipped by 180 degrees!
Cast Performance .358 200 gr is gas checked.
Where did this information come from? It is hogwash and absolutely incorrect. From no less an authority than Wayne Gibbs himself : "If a bullet is sized correctly and the lubricant is proper for the application, a gas check is absolutely unnecessary for any velocity less than approximately 2000 fps." This was told to me in a telephone conversation I had with the man about 12 years ago.
You might have heard of Wayne Gibbs; he was half of the Hensley and Gibbs mould business...
I have loaded Lyman's 358315, a GC 200gr RN for the .35 Rem., into .38 Spl cases over 12.0gr 2400 for my .38-44 HD. OAL was no problem in the HD cylinder when crimped over the front driving band. Substantial recoil, mediocre accuracy, never loaded another box since.

Check with Accurate arms.
The AA1680 will work just fine.

Hey all:
Back in the dat, the US of A army used the 200 gr. lead in the 38 S&W against the MOros....the 32-20 of the day didn't stop them. The 200 gr. slug TUMBLES in the 38 S&W load. Worked good!
HMMMMM....
Maybe this would be a good self defense load in the 38 SPECIAL, velocity of 700-800 fps!?
Back in the day, this 200 gr. lead was a POLICE round, too!
HMMM...

Even though the 200gr slug can be pushed at a respectable velocity in a .357(even at 1000fps,considering the small diameter it must punch quite deep),I doubt the normal twist of the S&W or Ruger will stabilize it enough to give good accuracy.That might be the reason why you can't find much data for it.
For my part,I'm satisfied with the 166gr slug my mould yields.And there's lots of data for loading 170 and 180gr slugs to start developping my loads from.
But if it's your cup of tea,be my guest.Afterall,experimenting is what makes this sport interesting.Just play it safe.

I have that load a+ at 50 yards open sights with my 19-3 long barrel but with 4227. Will try to post target when I get home. I got the info from the Lee manual and it works in mine. The target will be here if I can find it.XXXXXXXXXXXXXXXXX OK I FOUND THEM. I did find a 2400 load but at 25y. The 4227 made the same bullet shoot higher with the same bullet at 50 yards which I like with less recoil. National went out of business but I still have a few. ALL 200 grain bullets with a different shape will not group the same. I like Unique but it would not group with this bullet for me. Maybe a different shape 200 will work.

The 200 grain .38 S&W load was never used by the US military; it was a British military round from the WW II era. They eventually changed the 200 grain lead bullet to a somewhat lighter jacketed bullet.
The .32-20 was also never a US military round.
The cartridge that failed against the Moros in the Philippines was the .38 Long Colt with a 150 grain bullet. This led to the re-introduction of the .45 Colt for military use and finally to the adoption of the .45 ACP and the 1911 pistol.
