Yes, it's an optical illusion. The case is tilted slightly away (you can see the primer if you look close). That plus my filing of the edge is only slight on this one. Ed's rim is an indicated .045"; mine is .046". I aim for .042" but it's difficult to measure. Difficult to machine too, as I can't get any measurement without removing the case from the setup. I have to rely on a dial indicator. I'm working on a better way to index the case between the live center and the parting tool.

By the time I get it fully sorted, I'll have lost interest and gone on to something else...

Ah...I have no idea...
