Don't know why I'm jumping in here but I have been thinking of a "stopper". That's why I traded (on huntchat) for a Ruger #1 375 H&H.
I'll be hunting Elk in griz country for the rest of my life and I'd like it to be as long as possible, and just got to thinking that the 270 or 338 Win Mag may not be sufficient.
Was reading American Hunter where they took more than sever shots from a 375 w/270gr bullets to get a big brown finalized. Then I think it was 3 shots from a 416 on another one to ensure it was finalized.
Have a close friend that when he and the PH got done killing a cape buffalo it was on the order of 15 feet from them. Turns out the PH missed and my friend did the killing. He was using a 416 rem or rigby which ever is larger. The frontal shot in the chest is the one that ended it.
I suppose the 375, 300gr solid @ almost 2700 would be sufficient.
I'm trying to decide whether a 300gr soft nose bullet @ about 2600 fps or a 270 gr @ 2600 is sufficient for my insurance policy.
