Best tool to clean primer pockets?

None of the correspondents here has noted that the brass of the primer pocket expands as cases are fired, thus altering [decreasing] the ideal standard seating depth available to seat the new primer...thus enabling over time a primer not having the proper depth in the case.

That situation is not conducive to accuracy and may eventually create a raised primer and cause primer cratering from the firing pin [mimicing a non-existant headspace problem].

So, buy the Sinclair uniformer tool and related attachment to use in a cordless (battery operated) screwdriver...it works great.
 
I Make my own. It does a good job and no chance of messing up a primer pocket. It is not the fastest but if I am only doing a couple hundred rds taint bad at all.

For me, this is why the extra hassle of a Ultrasonic cleaner is worth it. The cases are spotless inside and out. Keeps your dies and presses clean too, other
than the de-capping station.
 
I suppose I could google it to save embarracement, but whats an "ultrasonic cleaner" ?

Maybe you should start a new topic about this and see who all chimes in.
