On my preference for large bore, flat nosed bullets for game shooting.
"You should use hollowpoints, and don't shoot anything too close. The hollowpoint won't have time to expand before it gets there."
To which I replied,
"So if I took a shot at a deer at say, 1000 yards with this 45-70, how big would the slug be at entry?"
Was answered with,
"I dunno but it'd be big. I tried killin' a deer real close with my 300, took 2 shots cuz the softpoint didn't have time to expand."
Seems to be a fairly persistent train of thought in this area.
