Mostly deer at 10-450 yards.
Maybe a Pronghorn hunt or three, perhaps even an elk or two, right at the same ranges.
Lots of practice to 600 yards at the range and to unlimited distance on public land.
Old guy, bad shooting shoulder and neck.
I realize no animal will ever know the difference, but Looneys do. :-) What do you choose and why?
What about the .270 WSM or .25-'06?
