Christensen Arms Mesa 6.5 PRC Question

Definitely some markings on multiple brass.

Hard to tell in the photo. You're looking for circumferential striations indicating a chipped or worn reamer, or they got a chip caught while reaming. Could also be a burr at the chamber mouth that they didn't clean up.

Do you have access to a chronograph? If the velocity is within reason, then pressure isn't the issue.

I do. I will check to see where I'm at next week.

Just an update after shooting my mesa again today. I scrubbed the chamber with heavy solvent and lubed bolt lugs and the heavy bolt lift went away!

I had this issue with my CA 300 PRC, it only happened when I fired to many rounds back to back. I am assuming the heat between the receiver and the brass were making things stick/expand. considering the PRC is a really a tight tolerance cartridge, I assumed this was normal with heat and the brass expansion. It has not happened to me again now that I'm a bit more mindful to take a break between shots..
