Thanks for the info, Unk. Yes I think 1" groups should be possible with this rifle at 100 meters even. But you are right about the wind. It really blows these little 17 gr bullets around. A 200+ yard kill with a rimfire is impressive enough to me. The longest shot I am likely to have on my terrain is a little over 100 meters. While I have 22s that can hit within 1.5" at 100 m, they are hard to use on varmints unless I know the exact range because of the trajectory of round. The flat shooting HMR is pretty much on the money from 25 yds to 100 yds aiming dead on.
