Vall,
I certainly agree with you in your statement that a barrel should not have to be returned because it was improperly done in a very dangerous way. The customer should not have to measure the bore and with the number of comments about how to measure the barrel and what appeared to be some lack of understanding how to measure the slug I have to say that I believe if the bore had been measured that the outcome would have been exactly the same. The gun would have been shot the exact same way. IMHO
As for JES I have a hard time understanding how they failed at the first attempt and apparently never measured their work either. Maybe their desire to turn the work around quickly lead to a very dangerous practice. Had someone been hurt, JES would no longer exist under their current ownership I would guess. Reboring and reborers were hurt by JES' failure to safe guard their customers. Not good. Not good at all.
