Several problems..........if you are hunting big game and insist on shooting grouse you will likely not see any big game.Cast pistol bullets in a rifle loads ...quiet and doesn't tear up meat........Hammond game getter difficult to reload juggling parts bullet swage rod wooden and broke 25 rds later.Will replace with a brass one.Also at 50ft hits 10" low from hunting ammo set up although in same hole.Fired .22 blanks both green and brown have to be removed with a knife not so good when several chickens are rolling on the ground in front of you laughing because you missed the first one.I have used them to finish big game including moose.Carrying a pellet pistol is a pain.
