I like to keep them and simply take the bullet out , remove all powder and deactivate the primer , they make perfect dummy rounds if theyre clean enough or simply a show piece for people i run into who have never seen firearms or ammunition before .
They make it able to start a very unique conversation ive already gotten many of my friends wanting to go to the range or get their licenses just from showing them my firearms and what the ammunition looks like , without the risk of introducing them to live ammunition in an unsafe environment.
