When I was growing up there were quite a few 303 British and 30/40 Krags still being used. And a lot of times the cartridge wasn't even mentioned, it was just the "high power" or "the deer rifle".
My uncle killed his biggest mule deer with the 303 in the early '70's, I don't know the model of rifle or if it even had a scope. What I do remember is that he killed it at the base of some river breaks and the only way out was up and he forgot to bring rope and his license and it was a long way from anywhere.
So he used his boot laces to tie the deer's ankles to a pole and him and his brother carried it out indian style on their shoulders up the breaks.
