I have a Commanche 45/.410 hand gun.
I made the mistake of buying some steal case slugs made in Russia. I have to remove the spent shell with a dowel rod.Not to hard to push out. Will shooting up the rest of these shells (20) harm the bore?

If the cases are sticking, I wouldnt shoot any more of them. One might stick tight. Not worth the risk. Does that gun work with other ammo? What about accuracy?
