Description Every A-Zoom snap cap is CNC machined from a solid billet of aluminum to precise cartridge dimensions, then hard anodized for ultra-smooth functioning and extended life span. A-Zoom snap caps are more durable than its plastic counterparts and built to spec so that they function through your gun just like real ammunition. A-Zoom 17 HMR dummy rounds are designed to teach safe firearms handling. They are not snap caps. They may be worked through the actions of any 17 HMR rifle for function testing. Dry firing will deform the head and will limit their use to 4 or 5 hits. Familiarize yourself or new shooters with your firearms before a round ever gets fired. This is a great teaching tool to introduce a first time shooter to the sport and get them comfortable with the handling and safety aspects before ever putting a live firearm in their hands.
