I'm not looking for a definitive answer here just an opinion. I have a 1920's vintage 10ga Parker with Parker Steel Barrels. The chambers have been lengthened to 3.5". The minimum barrel wall thickness at 3.5" from the receiver is about 0.105. Two questions:
1) Does this fall within the range of safe to shoot? (I have a VHE 12 that measures less at the end of the chambers and I shoot it all the time).
2) Is there anyone who will actually "proof" a gun or at least shoot it a few times in a safe environment of some sort?
