Why buy a blank pistol and ammunition to train just one pup? Use your over/under, side by side, or pump action shotgun to fire these 12 ga primed hulls only. (NO POWDER) These are now being required by most HRC hunt tests, and the word is that AKC and NAHRA will soon follow suit. They are quieter and easier on the dog's ears, safer and sold in bulk so they are much less expensive than actual popper loads. Sold in loose bags of 50. UPS GROUND SHIPPING ONLY
