12 Ga – 2-3/4″ Blanks – Winchester (XP12) – 250 Rounds

Bird dog trainers, field trial clubs, and event organizers need a shotgun report without a projectile. This listing is Winchester Super-X Popper 12 gauge 2-3/4 inch blank ammo, MPN XP12, sold as 250 rounds for gun dog conditioning, retriever and pointing dog training, field trials, and starting signals at events where a shotgun report is used.

A popper is a shotshell loaded with powder and primer but no shot or slug, so it produces a realistic shotgun report without sending pellets downrange. Dog trainers use poppers to get young dogs comfortable with gunfire and to mark the moment a bird is flushed or a bumper is thrown. Even without shot, a blank releases hot gas and debris from the muzzle, so it must be handled like any loaded shell and never pointed at a person or animal at close range.

These shells fit 12 gauge shotguns with 2-3/4 inch or longer chambers, such as the Remington 870, Mossberg 500, Benelli Nova, Winchester SXP, and break-action single shots and doubles. A common question is whether poppers will cycle a semi-automatic shotgun. They usually will not, because there is no projectile to build the pressure needed to work the action, so a pump, break action, or single shot is the practical choice. Another common question is whether blanks can damage a shotgun. Normal use does not, but clean the bore after use, since blank loads can leave more residue than standard shells.

Winchester XP12 is new production ammunition, not reloads, made in the USA. Each shell uses a plastic hull, metal head, and non-corrosive primer. This listing contains 10 boxes of 25 shells for 250 total from one lot, a practical supply for a training season with one or more dogs or for a club that runs several field trials each year.
