1. What is the chamber length?
2. What is the end of chamber wall thickness?
3. What is the length of the forcing cone ie. have the cones been lengthening?
4. What is the bore at 9"?
The barrels have been inexpertly honed, and the 9" wall thickness is inadequate, esp. for pattern welded barrels.
If you wish to use the gun, it should be with sub-gauge tubes.
