12 gauge action proving dummies for the 3-Gunner, Law Enforcement, casual shooter, and gunsmith who wants to check magazine feeding, action timing, extraction, and ejection. The only professionally accepted and safe way to check gun functioning; live ammo should never be used except in actual test-firing on the range - after you have checked the gun with dummies. 12 gauge, 2 3/4", Clear hull non-firing training ammunition with DUMMY stencil and a polypropelene insert at the primer pocket for easy identification.
SPECS: 12 gauge, 2 3/4 inch, 25 per box. Not SAAMI spec.
