That was fast! I received the K&N pocket uniforming tool today and it worked like a champ on the few cases I tried it on. I used it with the handle I ordered and it chattered and didn't smooth out the ring entirely so I chucked it into a 1/4" power screwdriver and gave it a few turns and it smoothed the ring right out. I did it until the bottom was just smooth. I want to shoot these to see how the pockets look after firing. I don't want to ruin a bunch of Lapua brass by buggering up the primer pockets.
