Hi all, I'm looking for recommendations on a good powder to make full power 357 loads probably shooting 158 grain FMJ or SWC. These will only be shot out of my 6-1/2" Blackhawk which should be able to take any abuse that I can give it. :lol:

Looking for good accuracy and a big bang. Muzzle flash is a plus, but not necessary. :wink:

I shoot mostly 38 special through my Blackhawk since it is a scoped target gun, but every once in a while, You just want to hear that really loud bang. :)

Full house 2400 loads should give you what you're looking for. Been shooting them for 30 years. Wouldn't use any other powder for 357.

Blue Dot is a classic for big flash and bang, and a little less prone to leading with cast bullets I've found than WW296 or H110. For FMJs, use what you want --- AA#9 and WW296 are good for a big pop!

IIRC the "classic" full-house load for 158 .357 is 15 grains of 2400. I believe this is considered "too hot" by today's standards* but it should be fine in a Blackhawk.

*Remember that a lot of smaller, lighter guns are now available in .357.

To find some real full power .357 Mag loads you might have to go back to some older loading manuals. The most recent ones are showing the downloaded castrated .357s loads.

I have read the same thing.

Being new at this whole reloading thing, I don't have access to those old books. I have to defer to you more experienced folks for this good old info.

For flash and in-your-face concussion style loads WW 296/H110 is the way to go.

Magnum primer, good firm crimp on a 158 grain jhp and 15.5 grains of H110 always gave me smile.

For more flash and bang, go with a 125 grain jhp and 20 grains of H110.

In 44 mag, the only two powders that I can get daylight visible flash is 2400 and 296. both with magnum primers and max loads. As I am rapidly getting to be and old phart that does not like the sound and fury anymore, I have dropped back to 200 gr cast and 6gr unique. But for real masichisim I still have the molds for 318 gr that use a dump truck load of 296. in my 4 5/8 this is an ahhhh $hit load and a half.

I'm way above that, and have been shooting those loads in Pythons, GP'S, and BLACKHAWKS for 20+ years. I use the older books when I want a real firebreathing load, but I wouldn't use them in any of today's 'light' 357 revolvers.

.357 mag full power 125 grain loads are nasty when it comes to muzzle blast and noise.

But I believe for the most bang, smoke and muzzle flash, nothing could beat a .45 Colt loaded with a full case of blackpowder, to about 900fps. (not the CAS whimp loads)

My pig hunting load is from Marshall Stanton (except I backed off .2 grains from his 16 grains)

185 grain Beartooth Bullet (LBT style)
15.8gr H110
Winchester Small Pistol Primer (Not Magnum)

1200fps from my 5" Smith Wesson N frame
1300fps from my 4" Ruger 6

This is a top end, no nonsense round that is asswhoopingly delightful on wild boar.

Normally a Magnum primer is not required for lighting up 2400.

2400, H110, W296, AA9, N110. One of these will suffice.



WARNING: Accurate specifically recommends AGAINST using Magnum primers under AA9.

You might try to hook up with some IHMSA (International Handgun Metallic Silhouette Association) loads. It taks a pretty stout 357 mag load to tip over a 50 lb ram at 200 meters. I recall seeing such loads in recent reloading manuals, which gives you a good excuse to buy some more books. You can't have too much info !!!

Those IHMSA loads are for single shot Contenders only, they won't work in any revolver.

I use Marshall's load as well, its very accurate and handles pretty well in my 6" GP.
