For the challenge I started using my .32 cal. muzzleloader, its a CVA squirrel rifle. I' ve gotten 3 squirrels so far this season with it. This little gun is pretty accurate out to 30 yards. I still will use my .22 cal. at times , but this muzzleloading is so much fun. I never used a shotgun for squirrels, to me it tears them up to bad and I don' t like biting into shot when I' m eating.
