powder for 357mag

[shoota280]

Looking for a load using 158gr RNBBs. Powders I have on hand are 231, ZIP, and Enforcer. Any suggestions, Thanks

231 works great

231 works great

next question is "How much?"

A paper loading manual is your friend.
(Winchester says start at 6.0 gr.)

231 is good but you wont get full power loads, close though

2400. I hate short answers but in my opinion when discusing powder for the 357, it's all that need's be said.

My "research" on .357 fuels started in the late 70s. These days I shoot most .357s with Herco. That covers me from 900 to 1200 fps. 2400 takes me from 1100 to top end...1500 fps plus.

H110/296 doesn't have any versitility. Those two are full on or nothing. And I've found I can get more velocity with 2400 and standard primers, than H110/296 with mag primers.

Blue Dot is great for snubbie .357s and defensive loads, but I still use 2400 for that.

231 and HP-38 are good, but they don't light as easy as Herco, and Herco is less dense, fills the case better and shows less position sensitivity.

Use what you've got. When its time to buy, try Herco. Now I'll tell you Herco will vary by a tenth or two when dropping charges from a powder measure, but you will not be able to see that over a chronograph. The better metering of 231 will not give any advantage over a chronograph due to its variation shot to shot depending on where the powder is in the case when it fires.

2400 fill the case and doesn't move at all. It also meters great. I love it.

If you're limited to the powders you mentioned I'd try the Enforcer.

Red dot. All the way

All of my 357's are also loaded with Herco. Find an older Lyman book and take a look at what Herco can do. I know that you stated 158gr.RNBB but I can get over 1200 fps with Lyman's 358429 (mine dropes them at 173gr.) and Herco with no preasure problems, I'm sure you could easily do the same with the 158 gr. RNBB boolit. Burns cleaner for me too than 2400.

With the powders you listed I only have experiance with 231 and that aint going to get you much power wise with the 357. Don't know anout the other two powders.

pretty much my thoughts on the matter.

Go to the HODGDON site or freebie booklets. Start with the Cowboy Action loads and work up. My current favorite is 5.0 TITEGROUP under various 158 grain LYMAN boolits or NOE 360 180 WFN plain base.

HERCO, UNIQUE, HP38 all work well in my mid range/generic loads for various VAQUEROS and Cowboy rifles in 357 (and 44 also.) Just starting with RED DOT/PROMO and some others.

Well it depends on what you are loading for... I use 2400, have for more years than I want to count. I hunt varmits and medium sized game with mine. If you want loads for paper punching, plinking and cowboy shooting....check out what the guys are offering up that do a lot of that kind of shooting...IMHO[smilie=s::redneck::cbpour:

I like Unique for plinking and 2400 for higher loads in my Smith M66. The more I use 2400 the more I like it!
