I agree with a lot of what other fellows wrote here.
The more I read Elmer Keith - the less I wanted to read Elmer Keith.
He sure seemed to have A LOT of trouble killing big game with "normal" cartridges.
I don't know why I've found the .22 CHeetah so good on deer, and the 25-06 and 7mm-08 so good on big game.
I guess, just like Jack O'Connor was, I must be a lot luckier than Elmer Keith was.
