12 Gauge Shotgun Shell Snap Cap Dummy Round Insert
For turning spent 12 gauge shotgun shells into snap caps / dummy rounds.
Simply punch out the primer from the inside out.
May have to drill/ream the primer pocket out - 6mm drill bit worked for me.
Push the inserts into the shotgun shell.
Fill the hollow tube with sand/gravel/etc to give it a little more weight.
Small amount of glue around the inner rim of the shell
Push the top insert into place - give it a light tap with a hammer to seat it home.
Enjoy!
