JB,
My point was this. Certainly, a .270 will kill a brown bear, an elk, or most anything else if you have time to pick your shot. Many hunters are quite comfortable shooting elk with such a rifle since an elk is unlikely to attack you. When a dangerous animal is hunted and a hunter's own skin might be on the line, I notice the small bore high velocity advocates become strangely quiet. Jack O'Connor, very wisely, armed himself with a big bore when the quarry was dangerous game. Reading both Keith and O'Connor's work, I don't think they were that far apart. Their clash was mostly one of personality. I have found recommendations from O'Connor for the .375 and ones from Keith for the .270 depending on the game and circumstances. Do you and I really differ on this? I read an article by you on the .375 a while back and did not get the impression you would arm yourself with a .270 for a grizzly hunt. I believe you'd agree the bigger gun is the more certain stopper.
