The shiny spot....
Sorry for not elaborating.
On the rounds that fail to chamber, there is a shiny spot on top of the case as if it rubbed on the roof of the chamber on the way in. Also, a tidbit I forgot to mention: when I experienced a round that wouldn't chamber, I had to beat the charging handle to get the action open. I couldn't pull the charging handle back with my hands.
Also, the rifle is brand new. It only has 162 rounds through it, including the 50 that were fired last weekend.
I splurged a bit and bought a RCBS small base die set today (its what was available locally, and much cheaper than the redding set). I plan on trying this, with a range trip planned this weekend.
