Indespensable for training with any shotgun - A-Zoom Precision Shotgun Snap Caps

I use these to test my shotguns before I take them to the field, after cleaning and reassembly, and for dry firing during training. For a pump shotgun, and to a lesser extent in semi autos,these will test the feed and extraction mechanisms, and for side-by-side or over-and-unders the extractors or ejectors. They are also good for dry firing the gun before storage to avoid damage to the firing pins.

These are among the least expensive snap caps that I have found, but they work very well.
