Was in my local gunshop last week that primarily does general gunsmithing work and who handles my FFL transactions. They were actually doing restoration work on a L.C. Smith a customer had brought in. Barrels were being polished and in the white. Anyway during the discussion I remarked I didn't know they did restoration work on shotguns and he said they only did a handful a year. So I then asked if they were going to change the chokes and he said they were going to open them up as requested by the client. Now, I know they don't have a skeets or other means of measuring bore diameter, so how can they open up the chokes with any degree of certainty? Am it to guess they probably just using the inside diameter of the current barrels at the muzzles and then removing enough steel that a drop in gauge gives the proper readings??
Also, in the opinion of the board, is this a common practice in what I'd call the general gunsmithing community?
PS. This fellow does outstanding general gunsmithing work, and builds 1,000 yard benchrest rifles in his spare time. I'd refer him to anyone on rifle and pistol work with zero reservations.
