A-Zoom 12202 Rimfire Dummy Rounds 17 HMR Action Proving 6-Pack

The A-Zoom 12202 Rimfire Action Proving Dummy Rounds provide safe dry-fire practice and function testing for 17 HMR firearms without the risk of firing pin damage. These precision-machined training rounds allow shooters to practice trigger control and cycling drills while protecting valuable rimfire mechanisms from wear.

What Makes This Different

Unlike snap caps that may not cycle properly, A-Zoom dummy rounds feature exact dimensional specifications matching live 17 HMR ammunition. The hard anodized aluminum construction withstands thousands of firing pin strikes while maintaining consistent chambering. Each round includes a spring-loaded primer that absorbs impact energy, extending firing pin life significantly compared to dry-firing on empty chambers.

Key Features

• Spring-loaded primer absorbs firing pin impact for extended component life
• Hard anodized aluminum construction rated for over 3,000 strikes
• Exact 17 HMR dimensions ensure proper chambering and extraction
• Bright orange anodizing provides instant visual identification
• Precision CNC machining maintains tight tolerances
• Six-round pack provides multiple training scenarios

These dummy rounds excel in competitive shooting preparation, allowing unlimited trigger time without ammunition costs. Law enforcement and military personnel use them for weapon familiarization and malfunction drills. The consistent cycling action helps identify timing issues in semi-automatic firearms while the realistic weight distribution maintains proper balance during training exercises.
