I’ll admit that I bought my Henry .357 Big Boy because I thought they look cool, and I already had guns in the caliber. After a while, I began to wonder how effective the .357 carbine was. As it turns out, they aren’t anything to sneeze at. Looking at reloading data, you can get within about 200-300 FPS of some comparable weight 30-30 factory loads. I haven’t tested all the load data, but I have no doubt that it is fairly close to accurate. The big thing, I think, with using the .357 magnum for hunting would be the bigger cross section limiting the distance. Give me some honest opinions about using .357 mag from a carbine for hunting within, let’s say, 100 yards or so. Is it viable? Will it humanely kill deer sized animals?
