Sendit6.5 Thanks for the reply. The once fired brass is measuring 2.270" from the cartridge base to the datum line. I am attempting to bump that back to 2.267." I believe that is well within SAMMI spec based on my measurement of factory ammunition. Since I deprime in a separate step, I do not have the decapping pin in place and the rod is up as far as it will go. As far as lube goes, I have applied a light amount on the inside of the case mouth using a q-tip. I have used the same style die to reload for my 6.5 Creedmoor and didn't have this issue. It's almost like the base of the die needs to be shaved off a tad. I'll give Redding a call tomorrow morning to see if they have any insight.
culater I will give that a try this afternoon. The brass was new AB Ammo, once fired out of my rifle. Unfortunately, when I insert the fire formed brass into the chamber, the bolt will not close with out a significant amount of force.
