Research letter & Barrel inspection clarification

[Rick Riddell]

On my research letter for a Damascus barreled gun it has the gun returned to the factory to have barrel work done, dents removed, cleaned and a reblue, as well as tightening the locks and action. I’m wondering what cleaned would indicate? Would this be removal of any Pitts? Perhaps in the process lengthening the chambers, as it now has 2 3/4. There are a few things that have me curious bit more perplexed 🤔 . I sent the barrels to Bachelder’s in 2017 to be checked for safety, it was reported as “ Brad states that these BBL's appear untouched and in original configuration. They will be safe to shoot with modern loads” through email correspondence and the invoice also stated safe to shoot with modern loads. So in 2019 in my infinite wisdom had the left choke opened and decided to get formal documentation on the barrels and to my dismay, although in acceptable range for safe barrel thickness they couldn’t give me any documentation on the safety of the barrels due to the lengthening of the forcing cones one at 7” and the other cone at 10”, and the tubes not at the nominal .729 left barrel at .736 and the right at .742 but in email correspondence I was told they were safe just no formal documentation due to the stated fact above. Now could I speculate that these “issues” could have been done at the factory when the gun was sent it for the documented work? Would Brad be able to determine these things were done through experience and the barrels would be acceptable or are there different ways of checking barrels for safety, loaded question I know. Any thoughts or speculation?
