RE: .17's
I have a Savage heavy bbl with a RB trigger in it set at 12oz. On a calm day it will group 5 shots, at 100 yards that you could cover with a dime. I have also used it very successfully on raccoons, squirrels, possums, ground hogs, and 1 mangy fox. Stick to shots under 150 yards, and choose your shots wisely and it will work fine.
