I suppose I didn't articulate the current status of the bolt situation. I am using a bolt and extension specifically designed for the .473 bolt face by a well known manufacturer that has been running this setup with rounds that regularly operate at 65k psi for the past 8 years. I am not using a standard extension, nor am I using a 5.56 bolt that has been machined to accept a .473 case head.
I appreciate the well wishes and concern.
Is this an ARP Super-bolt and extension? I think they make a .473 bolt and extension for their AR 270 cartridge. I would feel pretty good with something from them, based on their reputation.
