I think you'll need to borrow/buy a swaging tool. RCBS makes them, they press the primer pocket into uniform size.

It will be more practical to put the problem cases aside for now, and wait till you have a large enough amount to bother with.

I have deprimed lots of live primers without a hitch, just take it slowly for a start till you're comfortable doing it quickly.

Is this the tool you're talking about?

Why would you launch into using that tool if you haven't done some basic measurements to understand the nature of the problem?

Fair point. My understanding of swaging is that it trues up primer pockets regardless of dimension, ie cold forging the brass back to spec.
This is given that they're too tight/ distorted, not too loose.

I'd say that what you've posted above should be his first stop, before/instead of doing as I have suggested.
