Our trusted A-Zoom snap caps, perfect for training, now conveniently packaged to meet your specific needs. Get all of the calibers you need at a substantial savings over buying multiple calibers individually. For safety training, function testing or safely decoking without damaging the firing pin, A-Zoom training rounds are much more than conventional snap-caps. They are precision CNC machined from solid aluminum to precise cartridge dimensions, then hard anodized for ultra-smooth functioning and long life. In addition, each round has A-Zoom remarkably durable "dead cap" proven to withstand over three thousand dry fires while protecting the firing pin. A-Zoom snap caps last over 30 times longer than conventional plastic examples and are available in over 120 sizes from .22 Hornet to the .50BMG.
