The logic for altering the chamber from 2 1/2" to 2 3/4" is beyond my limited education. The gun is not designed for modern 2 3/4" factory loads and almost all of us know that. Removing more metal in the chamber area is not going to increase the guns ability to shoot modern loads. By insisting that this must be done, to make the gun "safe to shoot", implies that after alteration the gun will be safe to shoot with 2 3/4" shells. In effect that gunsmith is impling that his actions have made an unsafe situation into a safe situation. Talk about a legal can of worms.
He would be far better off to write every gun owner a short letter explainig the possible problems that factory 2 3/4" shell could pose in a short chambered gun and keep a copy for his file. Then he should leave it as is, he has covered his liability a-- and warned the owner. Why get that involved that you may cause a greater chance for failure by increasing the chamber to 2 3/4". $60.00 is not that much money to me or even most gunsmiths.
