Yeah I ordered a couple hundred of LC XM855 that came loose packed and nearly all of them had dents of some sort, while probably a 18-20 had sizeable dents. I tossed them into a little plastic container and set them aside. If the zombies arrive, and I run out of ammo, I'll use em. If not, they'll just sit there for a while
Just fine, if you reload look it over. It's how some round are formed when "fireforming" I used to do that with my converted .22k-hornet. Just shot regular hornets it would form to the chamber.
