Uniforming primer pockets on Lapua and Norma brass?

[40X Guy]

Just received my new 6.5X47 Lapua brass and some Norma .220 Swift brass. They both look very good, are very concentric and uniform. Do I need to uniform the primer pockets with this brass?

Thanks in advance

I usually do after the first firing just to make sure everything is good. Wouldnt hurt anything.

I did on my Lapua .22-250, oddly enough it needed cleaning up in the center of the pocket near the hole not in the corner which is typically where pockets seem to need it at least from my experience.

I use the Sinclair tool every time to clean the pockets. About every other firing, the tool removes a couple thousandths and always leaves the pocket perfectly clean. YMMV

I went ahead and primed the cases (Norma) without uniforming, I will uniform after first firing with my Sinclair uniformer, thanks for all the fast replys and help!!
