not sure about the bushnell. Are you talking bout one of the little ones like the sportsman or one of the "military" grade scopes like one of the trophy or halo styles? we used a sportsman and a BSA 50mm on a DE .50cal and it didnt work at all. Way to much recoil for the little guys. Mind you this was a 50cal not .44 and depending on barrel length/recoil you may have better luck.
