See pics. It was still snug on the muzzle. I check that before each 3 round group. Happened on 12th shot of the day. Was working great on taming a 300 WM.
Ideas on how to check the threads and shoulder for square without pulling the barrel????
That sucks! I'm not sure about checking the shoulder for square, but I do know they make rods that you can insert into the barrel to check alignment through the can.
I just ordered rods from McMaster-Carr to cover .22LR, .223/5.56, 6.5 CM and .308, they cost less than $6 ea. They come in 3' or 6' lengths. I bought 3' and plan to cut each in half so I can give my buddy a set. I actually have a chart that list the caliber, dia and McMaster P/N. If someone sends me a PM, I'll send it to you and let you post it. I don't have a photo sharing site.
Here's the part numbers:
.22LR McMaster P/N 8893K191
.223 McMaster P/N 8893K193
6.5CM McMaster P/N 8893K204
.308 McMaster P/n8893K219
