I have started reloading 223 using cartridges that I shot with my AR. I am using a Lee single stage press and noticed when starting that sometimes the small rifle primer seated easily and other times not. Looking at the ones that seated easily i found the primer hole clean and looking like it was formed when the case was manufactured. For the ones being more difficult I see what looks like the outside of the primer still in the case. It almost looks like the original primers had two outside bands around the primer. When the primer was removed with the press it less the outer most ring inside the case. It makes it harder to insert the new primer. The cases are stamped LC that are the problem. Has anyone else run into this issue and is there an easy way to remove the ring left inside the primer pocket?
