Long range shooting or hunting? I don't think of Vermont as a long range hunting state, but I don't hunt there. If I thought I needed a big bullet I'd be looking at .338s and deal with the recoil, if not I'd be very happy with a rifle in the .280 to .30-06 range.
If it's long range shooting, he might consider 6.5-284 which is a long range match winner.
