Ok
I'm not about to try to reload (remanufacture) 22 lr's..but......
How are they manufactured originally??

Thinking about it..........................

The stuff has a "rim" (>> rimfire) which appears to be a double fold of brass material consisting of the base of the cartridge on one side and a very short second side folded over with (I would suppose) a small amount of priming material sandwiched between the two folds.

How do they do this mechanicaly?

How do they manage to pinch the primer material between the two folds of brass without setting it off?

renaissance wants to know.................

As I understand it ...
The priming compound is a liquid.
They drop a bit in the case and spin it.

Poof. You have primed a rimfire.

Not really a liquid. More like a gummy paste.

It's placed in the rim using centrifugal spinners.
