marlin .22 bolt action, I actually put 3-9x tasco deer scopes on them, as I like the reticles a lot better and I have taken squirrels over a hundred yards with this combo, which I couldn't do with a 4x scope. Marlin .22s are relatively cheap, and with each long distance shot I'm amazed at the accuracy. I have taken a few rabbits while squirrel hunting with a .22, but I never purposely seek out rabbits.
