I have a CZ in 17 HMR and I didnt have much to spend on a scope. I bought a Cabela's brand, specific for 17 HMR. The optic quality is so so. What I like about it is that it has a 3rd turret; so once you have it sighted in for say 100 yards. You just dial in the yardage you're shooting the critter at; they're toast! Either know your distance or use a range finder. It works for me.
crows, magpies, poopy pigeons and gophers are history!
