I've had excellent results/accuracy with Missouri Bullet Company .358 Diameter "Striker", 180 grain RNFP Bullets, Brinell 18 with H110 at 13.5 grains. No gas checks and no leading in my Dan Wesson .357 Magnum with 6" barrel. I started with 13.0 grains of H110 for this weight bullet and worked my way up to 13.5 grains on the recommendations of someone on this site that had used this in the past.

Hello, Crankgrinder. When I was competing in IHMSA, I shot a S&W 8 3/8" Mod. 27 for over two years, with the Lyman 357429 & H110.

H110 is an excellent high-performance choice for 357 Magnum, but I suggest it best for bullets 140g and heavier.

I used H-110 with 158 grain Speer jacketed bullets. It was a strong load. There is not a wide margin of top-to-bottom load range so be mindful of what you are doing. Definately start at the low end and work up.

There are three powders which perform very well in my 357's with cast bullets and jacketed bullets: 2400, AA#9 and W296/H110.

W296 and H110 are the exact same powder so buy by price.

You cannot down load H110, you can 2400. AA#9 is not recommended to cut loads.

I do not recommend Blue Dot, it leads horribly with cast bullets.

14.0 to 14.5 grains and a 150 or 158 plainbase bullet is good. The 296 load is in the WW booklets around 14th edition. Firm crimp and magnum primers. Both H110 and WW296 are made at St. Mark's in Florida. Same powder, different can.

thanx folks and this is all great to read. i currently load 2400 and its cheaper for me to wait till a gun show pops up here and go to it and buy my gunpowders as none of the gun shops here seem to carry reloading supplies. i usualy get whats most available. currently in my powder supply i have 2400, power pistol and blue dot. my .357 cast bullets are 158 gr rn. i am also looking for a good powder to load .38 and 9mm in cast loads also.

2400 is excellent.
Suggest start under 158g of 12.0g, non-magnum primer.

For mild/medium/performance 38 Special and medium/performance 9x19 recommend Power Pistol.
Very high accuracy potential in both.


Most highly recommend Blue Dot be reserved for medium-weight bullets in 10mm.

tricky

I keep on hand over twenty powders for loading 'handgun' ammo.

Power Pistol is an ideal choice for the 9x19, and the big factories use its commercial equivalent ("Bullseye 84") to make much of it.
It also offers great accuracy potential in the 38 Special, but not in the conventional-thinking 'old way' of 148g swaged wadcutters.

W231/HP38 (same powder) is ideal for low-velocity 38 Special accuracy goals, but I consider it too 'fast' in burn rate for 9x19.
Green Dot is not on my shelf.


My best answer is I choose powders based on my specific performance goal for the load at hand.

I think Win. 231 is hard to beat with cast bullets for 357. Now full power loads oon 357 get Win. 296. Works great is 3, 357's
