Correct me if I am wrong but wasn't 296 the original powder for the M1 Carbine?
357 + H110

You are correct, H110 was what they called it and it was the original powder used for the M1 Carbine ammo but as we all know now H110=W296...

Have been using H110 in my 357 loads for 30 years.
Never chrono'd the pistols but my Henry Big Boy sends 158gr XTP's over 1700fps with 16.5grs and CCI 550 primer.

I don't have a chronograph to verify this but I have often wondered if Alliant 2400 would perform better than H110 in a 357 magnum with a 4" barrel or shorter using a 158 gr bullet . When using a 6" barrel 357 , then i would guess H110 pulls ahead some in velocity . In a rifle with a 20 " barrel , no contest there it would be H110 by a landslide . Of course not all chronographs agree so there is that . Regards Paul

I'm getting ready to chronograph several loads of H110 with 140 gr. FTX is it Hornady's. And compare 2400 to H110 with 125 gr. XTP's. 4" S&W mod 19
Looking forward to reading your range report.

A word of caution, if your model 19 is an older classic model. My buddy was enamored of high velocity with 125 gr bullets and loaded his 4” with H-110/W-296 at loading manual maximum charges and wound up with a cracked barrel at the forcing cone. (A known weak spot in the original design of the Model 19/66). S&W suggested that they be used primarily with .38 Special loads and only occasional use of .357 Magnums and then with 158 gr bullets, as the lighter weight bullets put more stress on the forcing cones. The newer models have been redesigned in that area and are supposedly more capable of sustained magnum pressures. (FWIW, my old Ruger Security Six digested a lot of those loads without a problem, but I quit using them after the Model 19 disaster). If I load 125 gr JHP bullets now, I use Unique, Accurate No. 5 or Power Pistol. Seems to work fine in the SP-101, GP-100’s and S&W Model 28.

It's not the magnum load which cracks the forcing cone, it's the super high velocity generated with a 125gr bullet over the 158gr bullet.
The original M19 can be shot with 158gr Cast bullet Magnum loads all day long without effecting the forcing cone.
Hopefully the OP has the newer model if he wants to shoot 125gr jacketed bullets at magnum pressures and velocities.

I've been playing with various powders for my 357 loads. I have found that H110 is very unpleasant in a Scandium framed 360, not bad out of my 66-8, and fun from my 6" 686. I've loaded with H110, VV N110, VV N340, and some universal. VV N340 makes for a very nice moderate load, still snappy out of the J frame, but comfortable in everything else. My favorite loading is 17.2 gr of VV N110 under a 125gr FMJ. at 20 yards my 66 and 686 just make a ragged hole. The muzzle flash is still impressive, but not to the same level as H110. The last time I was at the indoor range the guy in the lane next to me stuck his head around the wall and was curious as to what I was shooting, he could see "a fire ball" every time i pulled the trigger.
