I just finished pillar and glass bedding the action on the #2 rifle today in a new Boyd's Pro-Varmint stock so after it sets up for a couple of days I'm going to head to the range with more test loads. I'm looking for bug holes.
I have Lapua brass and a separate Redding FL neck sizing die set up for it and Starline brass with it's own Redding die. Both only bump the shoulders 0.0015. This issue with the peened necks was a new one for me so I thought I would share it. If nothing else I hope that reloaders will learn to try a new round in the chamber before they load up a 100 of newly sized cases. I know I sure will.
