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.
Reloading .357 Magnum Page

I only have H110 and A2400. That's why the choice of powder.
Well, since
1) H110 is one of the powders you have, and
2) the link above includes a recipe for loading with W296, and
3) H110 and W296 are the same thing

It looks like your answer is to be found at that link that Hawker Man posted.....
 
The reason there is little data for a 200 gr. bullet in a .357 magnum may have something to do with the OAL being too long if seated in a cannelure.
They will fit in a 19 but a 27 cylinder is shorter. I also had to modify my seating die to keep from putting marks on top of the nose of the bullet.

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...
smokem
Actually, that would be the .38 LC round, not the S&W and certainly not the S&W Special round.
.38 LC pushed a 150 gr. bullet to a MV of something like 750-800 ft./sec.
The Moros wrapped their chests in wet leather, tightly. The bullets bounced off like they were shooting steel.
The Army's answer to that problem was to return to the .45 Colt chambering for the New Service revolver.
It was the ENGLISH that loaded 200 gr. bullets into the .38 S&W round, during WWII.
The infamous ".38-200", it was a like a mini .455 Webley round.
The Enfield #2 was the gun it was chambered for. This was at a time when the Enfield was replacing the larger Webley Mk.VI.
The Enfield round was also farily enemic, but the Brits found out heavy bullets moving at moderate speeds were more accurate and tended to do more damage to their intended "targets" than lighter bullets travelling faster via the 1905 British Army tests.
....this gives creedence to a 200 gr. .38 special / .357 mag load as being highly effective.
Load for accuracy, instead of power, and let the big heavy bullet do all the work.
I would shoot (sorry) for around 1100 MV with a 200 gr. bullet.
This should yield a ME of about 537.5. Very close to the original .357 load, but the heavier bullet will carry much more momentum as it passes through heavy clothing and bone, thus creating a more destructive (and deeper!) wound channel.
The heavier bullet will also carry more energy out over longer shots.

I have some 200gr lead with GC. I think Cast Performance. Stroked with 12.5gr H110 I was getting around 1300 FPS out of a 8 3/8”Model 686 and around 1250 FPS with my 8 3/8” Pre 27. It’s a handful but a good hog hunting load. I’ve since changed to 180gr Coated Lead from Missouri Bullets. Cleaner and more accurate at 50 yards
 
Which half?

Stop it. I don't want the mods to close this thread.:D
It's got some interesting stuff.
(How did those Moros breathe with their chests tightly wrapped in wet leather?)

Chic Gaylord suggested in his 1960 book Handgunner's Guide, that .38 special cases Unique powder and hard-cast 200 grain bullets be used for a similar load.

He also emphasized that it was for heavyweight revolvers only.
 
USE THE DATA BELOW AT YOUR OWN RISK, sneak up on loads using chrono and all safe loading practices.

Here are some chrono results:

The 200gr Leadheads listed below is visually identical to the Cast Performance 200gr

Labradar Muzzle Velocity (familiarization run)
60 Deg F
S&W M66-8 2.75" .357 Mag

180gr Buff Bore …………………………………………………………………………….. 1,312 fps avg ( 6 fps ES) -- two rounds
185gr LFNGC (Beartooth), 15.0gr Lil'Gun, CCI 400 New Starline.. 1,228 fps avg (14 fps ES) – two rounds
200gr WLNGC (leadheads), 13.4gr H110, Fed 205, New Starline.. 1,102 fps avg ( 4 fps ES) – two rounds
200gr WLNGC (leadheads), 14.4gr H110, Fed 205, New Starline.. 1,155 fps avg ( 2 fps ES) – two rounds
(purported to be the “Doubletap” load info)
200gr WLNGC (leadheads) handload with Lil Gun ………………………. 1,266 fps avg ( 2 fps ES) -- two rounds
Load data not given -- maybe too much of a good thing. Spent cases fell from chambers, and no obvious signs of over pressure. Recoil was heavy. Don't even know if this stabilizes.


Another data point (may or may not be useful)

11.0gr A2400 under the 185gr WLNGC shown above gave 1.140 fps from 5 1/2" Freedom Arms M97 (5 long paces from muzzle (old competion electronics not Labradar) and 75 deg F)

I know this post is a few years old but I have the Lyman 195 mold. A heavy boolit really kicks. I AM BORED so here are a few photos. The 200 national has been the most accurate for me but they went out of business. WINCHESTER used to make a 200 grain bullet. This is a 1983 photo in the handbook.

Wayyy back in the day... 195gr loads were listed in .357 Mag data.. Actual weight of a cast bullet depends largely on the alloy used..



2400 should get it moving pretty well..
Looks like Herco is the speed demon there.
What is the asterisk for? Max load?
I like that Unique "accuracy" load. 942MV @ 195 gr. = 384ME
Good power and likely a mild shooter....and...accurate. -b
