I was given a bunch of brass with crimped primers in 223 a while back. Today I picked up a Lyman primer pocket prep tool that has a gizmo for removing the crimp. I've only done one so far, and find that it puts a heck of a bevel on the pocket, way more than any commercial primer pocket has. The tool was on the sale table at the local store and did not have any directions with it. I took a chance that it is intended to bottom on the pocket to give a consistent depth of cut; can anyone who uses this tool confirm if indeed correct? I compared the tools that came with it to pics from the Midway catalog and everything is there that they picture. It was easy to do, I'm just worried that I'm going too deep. Thanks for any help you can offer. Ken
