A-Zoom 2-Pack Precision Snap Caps fits 7.7 x 58 JAP
For safety training, function testing or safely decocking 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's 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.
