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. Use them for safety training, function testing or safely de-cocking without damaging the firing pin. They are safe for dry firing practice for cowboy six-gun and lever action dry firing practice drills. They're also great for quick Draw practice, too.
