Did he back bore it or ream out the chambers to 2 3/4"? Did he hone the barrels to clean them up? Did he measure the wall thickness to be sure the barrels are still safe? These are the questions I would want to know the answers to before I shot that gun. Some gunsmiths use the wrong word or phrase to describe what they did. Not sure if they don't know the correct one or want to make minor things seem major and the price charged a bargain.
