[QUOTE="royinidaho, post: 166246, member: 2011"] Hmmmmm, never had that happen. The symptom would seem to me, whether you are fire forming w/corn meal or w/a bullet, that you may be NOT leaving the dime's thickness just a head of the shoulder when necking down. Not doing so would allow the firing pin to push the whole cartridge forward to the thoulder and when she goes bang the primer moves before the case comes back. That's just my guess. Ask Kirby. He'll know. If the primer pocket is loose after the fire forming, I wouldn't know what to do. Maybe get lighter corn meal.:D The next thing to check w/the nosler brass is once fire formed and before resizing (Kirby says to full length resize, just don't push the shoulder back) does the bullet "fall" back into the case mouth? All of mine did. This was my second problem with the nosler brass. Also, I'd stick with the 169s. At your elevation I'd start w/a sea level bc of 0.74 or 0.75 [/QUOTE]
