Old Military Brass and new primers

[tlk]

Have some old new winchester military brass. 1945. New primers wont fit in due to a tight "ring" at the mouth of the primer cavity. It is also real loose past this ring. Has anyone reloaded this stuff? Are there tricks to it?

Thanks.

Military primers are crimped. That is the "ring" that you see. RCBS, Dillon & other companies make swagers/cutters for removing this crimp. If you only have a few to do you can sometimes get by with a chamfering tool to remove the "ring" or crimp. Military match brass does not have crimped primers.

Thanks. Used your lead and found what I was looking for at Midway. Also found this video.

Works with a deburring tool, but it seats with force and doesn't help my nervous tic any .
