Thanks Franc.
Lots of news, but I still need to measure wall thickness of everything I can get to at the rupture.
The first spot where I can measure the bore is at 3 1/4" and is .750, then 3 1/2" .737, and 3 3/4" .733 where it remains uniformly until the choke constriction starts at 3" from the muzzle. Clearly the barrel expanded as it ruptured, but not like this
The first place I could use the wall thickness gauge was at 4" and it was .112, about the same as the end of the right chamber. At 5" .096 and 9" .060.
9" from the muzzle .039 and MWT was .037 at 5".
After serious cleaning, all the rust came off easily and the bore is without significant pitting.
Will get more pics up, and STILL trying to get a better pic of the extractor indentation on the steel head.
Bottom line: I think the barrel is still at factory specs and
we can't blame thin anything, but again will report the wall measurements around the rupture tomorrow.
