I don't own a contenter nor am I likely to, but when reading Fur-Fish-Game, the shooting editor has written several articles on bunny busting with that weapon and a 410 barrel, and I think a 6 gun that is for 410...here my rabbit hunting is done with a .22 hornet, my pal tried beagles in this country...had a blast until a jack too his beagle out of hearing just at dusk...he figures the coyotes ate it...too bad, nothing like beagles and bunnies.......
