My father bought a #1 in 357 only to discover the previous own had lengthened the chamber to 357 maximum and did it with a chucking reamer. At that point the damage was already done so he had a gunsmith clean up bubba job with a proper chambering reamer.
It was a neat rifle but not what he thought he was buying - and later sold off.
