10x 12 gauge shotgun cartridges dummy snap caps training cartridges dry training

To convert used 12-gauge shotgun shells into practice rounds/dummies. Simply punch out the primers from the inside out. You may need to drill out the primer pocket – a 6 mm drill bit worked for me. Insert the inserts into the shotgun shell. Fill the casing with sand/gravel/etc. to give it a bit more weight. Some glue around the inner edge of the shell. Press the top insert into position – lightly tap it with a hammer until it is firmly seated.Color of the printing material may vary.A set consists of 10 pieces for self-assembly.
