.357: 125-gr and maximum H-110, bad for the gun?

    I have some of these left over from experimenting with different loads. I'm wondering if shooting about a thousand of these, loaded with max or close to max charges of H-110 would result in flame cutting the top strap of my S&W revolvers or faster than usual forcing cone erosion.

    The top strap will reach a point and stop. The forcing cone will not stop. Took me about 2000 to eat the forcing cone on the Python. 125 Sierra and a lot of WW296.

    Oh geez. 2,000 rounds is only about a year of shooting for my .357 revos...

    I feel better keeping that load at 1350 Fps or lower, that's
    Just me though.

    Loading like that is hard on all guns but harder on some. Keep them out of your smith I would say with the possible exception of the model 27

    I have no doubt that running full tilt loads with a light bullet like 110's or 125's through a medium framed revolver, is considerably harder on the firearm. But in all honesty, I've been almost exclusively running H110 / 296 with everything jacketed from 110's - 158's for decades, and I haven't really noticed anything unusual. I'll add that I have two K frames that have had a good 3K each of this load make up, I estimate that at least 20% have been either 110's or 125's.

    My question is, which S&W revolver are you shooting?

    All of my 357s are N-frames. But, what does frame size have to do with forcing cone erosion?

    CPLofMARINES Well-Known Member

    Typically , the larger frames can withstand the hotter
    Loads. But, remember it's not how powerful the round is,
    It's all about the size/weight of the projectile, when you
    Are talking about flame cutting and forcing cone erosion.

    Old K frame Smith's forcing cone is thin at the bottom and has a tendancy to crack. Your results may vary. The choice is yours. It's your gun.

    When the K frame was developed there were no 125gr jacketed bullets screaming along at over 1800 fps so the K frame's forcing cone was a little light for that development. Some of the K frame magnums suffered cracked forcing cones because of the beating they were taking. The L frame was developed to fix that problem. The N frame never had a forcing cone problem because it was beefier than the one on the K frame. Erosion will happen to any forcing cone, it was the cracking that was the major problem.
