Snap caps are a great tool for practicing almost all the same drills you can do in a live fire session, and offer many benefits over dry firing on an empty chamber. Click-Click-Boom has a huge variety of snap caps that we keep well stocked year round in many different calibers ranging from .223/5.56, 9mm, .22LR, 20ga, and everything in between. Snap caps can provide a huge range of benefits for shooters including beginners and advanced. Practice loading, avoid jams and practice handling misfires, practice trigger work, and dry fire your firearm without damaging the firing pin or any other mechanism in your gun.
