Buy a good rail. If you are thinking about going over 150 yds, buy a 20 MOA mount. You can still shoot 50 yds with this set-up.
I use all kinds of scopes on my rim-fire rifles. Vortex, Sight Mark, & a few others. I don't go overboard on price for these rifles, but a NightForce or U.S. Optics really isn't overkill, but not exactly necessary for a rim-fire. I tried my NightForce scope on my Savage MKII TR & while it preformed very well, I decided it needs to stay on my .308.
I read a review on this scope nikko stirling targetmaster 6-24x 56mm this evening, & i'm thinking about ordering one tomorrow.
WalMart sells those Center Point scopes and thew preform pretty good.
Good luck in your .22 shooting. You will have a lotof fun & learn many things without spending a lot of money.
