No, the tool I was talking about making is the ram that goes inside the case to support it against the primer pocket swage.
The ram on the Dillon swage is flat on the end and I'm thinking that if there is a protruding burr from punching the flash hole
that the ram will flatten it and restrict the flash hole on the inside. Making a ram with a dimple on the end should decrease the
chance of that happening. Going back over the problem, I experienced it with some of the commercial brass that I didn't run
through the pocket swager. That tells me that it probably came from the factory that way. I thnk I will still make the ram.. Blitzfike

Gotcha... that makes sense and I'd bet that you're right about the case support arm pressing any burr or flat back against the hole.

I've never used the dillon press but people have good things to say about it.
