Construction
Gas checks are most commonly found in the form of a thin cup or disc made of copper, zinc, aluminum, or a suitable alloy such as brass. The bullet that is to be gas checked must be designed for a gas check. If the bullet is designed for a gas check, there will be a rebated area to allow the cup to fit onto the base, or a small projection to allow attachment of the check. The check is swaged onto the bullet, covering most or all of the base; the perimeter is the most important area, so some designs (such as Corbin's Base Guard(tm)) use a short cylindrical projection of the bullet base as a rivet to lock the check in place. Once assembled, the bullets are loaded normally.
