Im currently debating on the charge for my 357 carry ammo. I want it hotter than 38+P but dont need a full 1300fps on a 125 grn hollow point (usually measured on a 6” barrel). My snubby Dan Wesson will probly only produce 1000 fps with that load but the flash and recoil are just wasteful, after all, Im not really trying to impress the bad guys or blind myself to my second shot, I just want reliable expansion at about 950-1000 fps and enough more “bang” to let any other bad guys around that this guy aint just packing a pea shooter.
Taking my barrel gap from .006” down to .003” to conserve escaping gasses, might get a few more fps on a smaller charge. I need the weather to cooperate so I can get out and test some of this!
I think I’m gonna call them “Humming Bird Feathers”.
My .357 big game load is 16-17 gr of IMR 4227 with 158gr hornady XTP. It is right around 1100 fps 4” Bbl smith model 17. I’ve used it for coup de gras on whitetails. Never for takedown. A little too big for hominids. Better with the 125 gr which you speak.
