Lapua - Uniforming primer pockets

Not needed,in fact I believe Jack Neary in his gun tuning videos states that in their testing it made groups a little worse to to rework the primer pockets.
 
They are damn near perfect to begin with. I also found that carbon flakes out of Lapua primer pockets easier than any other brand of brass with a simple primer pocket brush. So uniforming to clean is superfluous as well.
