No matter you reload or do not reload this is an inexpensive tool you can safely use to unload cartridges you do not feel comfortable shooting. There are many different brands.
And please note. The law of: "for every action there is an equal and opposite reaction" is why bullets fly. The action of powder burning forces the bullet out of the brass. With the brass loose-not contained with a chamber-the bullet will not fly with any vigor and neither will the brass. Once the bullet escapes the brass the burning powder will exit the brass into the atmosphere where it can expand to its heart content and not against the base of the bullet.
Nonetheless, if you think burning bullets is fairly unwise, unload them using the tool above. Or, given them to someone who can.
