I'm looking for a scope, as well, for a semi auto 22WMR. I have settled on a Leupold 2-7x28 VX1 rimfire. The parallax is set at 60yd on the rimfire version and they are very light weight. I'm ordering it because of the weight, but all the other specs and features work well for my application. I'm not sure how fine the reticle is, I haven't ordered it yet.
