I believe he's asking should he lube the primer pocket while swaging/reaming? I ream.. so no lube necessaryNope, no lube for decrimping on my end. Swage or ream, no lube. That assumes I understand your question. Where would you apply lube for removing crimps?

When I swage (decrimp) mil brass I use no lube. I use the CH4D swage and prime kit to swage my crimped brass with excellent results. I recently swaged app 1500 rds 223 brass in about 4 or 5 hrs with this tool on my single stage press. I feel it is THE fastest way to remove the crimp.

Elbow grease.
That's it. Just a few thousandths cut out of the primer pocket mouth. You can see the crimp, and see when it's cut out. You'll have to really bear down on the case and remove a lot of metal to ruin a case with a countersink! Been doing it this way for mebbe 26 years...So if I go down to Lowes/Home Depot/whatever and pick up a counter sink, put in on my cordless, this should remove the crimp just the same as using my chamfering tool. Did I read that correctly MDI? Heck, get the one with the drill bit and clean out the primer flash hole also. Way to simple, there needs to be a catch.
