I don't know if they are still available, but the Weaver 4-16 x 42mm has semi-target turrets and tracks very well when changing powers. It ain't no Leupold Vari-X III, but it's a good scope for the money. I still have one left that I intend to mount on a CZ-452 in 17 HMR when I get it.
Man, how could I forget the Weavers. Very rarely do I regret getting rid of a rifle or pistol. Every once in a while one gets away, and that was my CZ HB 452 in .17 HMR. I can not count how many p-dogs and rabbits that sucker took. In fact, I might try to get it back from the guy that has it now since he is taking a fancy to a couple knives.
