Depends on how far the target is and what size the target is. If it is small and far away you need some high magnification. On my 22-250 i have a 6-20X50 scope mounted. If the target is big or close i can dial down the mag. If it's small and far away i can crank it up. As far as reticle, stick with fine croos w/target dot, or duplex. Mil-dot scopes work great. But you have to know how tall the target is, and count how many dots then do the math in your head. Takes to long if you ask me. Hope this helps.
