Brand new to reloading and am looking for components while waiting for my reloading equipment to arrive. I was looking at a website that sells once use brass for .223 and they have some. It says "Federal 223 FC Crimp (250ct)". Can someone tell me what Crimp means?
I comprehend how a projectile can, “lose velocity", but don't understand how a projectile can, "loose velocity".
