I have always wanted to get a lever-action rifle, essentially a 94 and had always thought of 30-30 as the caliber.

I plan to use it only in some specific deer hunting situations where the range will be inside 100 yards; ideally around 50.

Anyway, a friend recently got a lever action in .45LC, with which he took a deer with a single shot to the head. It is a pretty gun but is the .45 not really enough for a body shot at 75yds?
