A-ZOOM Action Proving Dummy Round 22 Winchester Magnum Rimfire (WMR) Aluminum 6PK

Precision CNC machined from solid aluminum and hard anodized. Rounds are designed to teach safe firearm handling or they may be worked through the actions of a firearm for function testing. These are not snap caps but functional dummies. Great for gun testing and shooter training. Dry firing will deform the head and will limit their use to 4 or 5 hits.
