I bought a bunch of .357 magnum ammo while set up at the gun show this passed weekend (cheap). It was a big variety of brands, weights and bullet types. Among the boxes was some Cor-Bon 200 grain hard cast. The box says 1200 ft/sec and 640 ft/lbs. That's a big hot load! Has anyone fired that stuff from a 4" N frame Smith, or L frame? I think I'll keep it away from my K frames. I think it's designed for deer hunting, but what do you think about using it for SD?
