I have a Ruger American .22 Mag. I have it zero-ed at 100 yards with CCI 40gr. bullets (all types of CCI 40s seem to shoot to the same place). I have a 3-9x scope on it, it shoots pretty well.
It hits about a half-inch high at 50 yards, and about that, low, at 125. I consider that, "good enough", for my needs. I have been pretty happy with it, and it's slick, and handles well.
This, I got the compact RAR, 2-7 leupold, I run the 30 gr Sierra federal premiums, accurate lil kill gun...
