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.
