Thanks Dan, Rick and Gary.
Gary basically yes but I did change 2 things. Went back to my Protector Single Stitch leather bag with a donut under it and using a used dryer sheet folded in half twice under the rear of the butt. Also, I changed the front back from a SEB bag to a Protector Cordura. Something about the springiness of that bag that I thought may be causing issues.
The load was the exact same load as in August. 53 clks of 133, 64.5 Opel seated at the Boyer/Neary meathod of bullet jam. Bullet seated out to the point the lands pushed it back into the case. Shot it at that. I have a new respect and faith in this rifle.
There is a lot more I can say but I will leave it at this. The lastest bolt mod, leave the firing pin unscrewed from the bolt body but still stuck inside the body. Open your bolt case, grab it by the handle at pull it out forgetting that the firing pin is loose. You hear something bounce on the concrete. There you see laying on the cement is your SHINEY firing pin. As you drop the F BOMB wondering if you bent it. Cal's thought on that, I tell everyone I indexed my firing pin to 6 O'Clock....... You should see some of the looks or comments.
