Pre-frag! .460 prefrag elephant load. Speaking of Jeff Cooper, he talked about how there was rave reviews over the .380 Gaser slug and now terrable the damage it did on just about anything they shot. He wrote, "why if that's so, let's load a .45 version and hunt elephants!"
He said this in jest, as unlike gunkid, he KNEW there is more to stopping power than just energy. Way way more than just how much energy any cartridge produces.
And gunkid, the CAR is a losers rifle. The Army in Vietnam found that out and they dropped it. I'll take a 9mm carbine over a 11 inch CAR any day. It's that much a POS.
