the fact that many production guns are not adequately regulated is a reality based on quality control.

the cure for that disorder involves mastery of sophisticated tools, and that is artistry.

Or another possible cure is a redneck with a file. 😀

I have found it pretty easy to move poi with a file, but the problem with that method is that you can only center one load. If it's a single purpose gun, like a turkey gun, that's not that big of a deal to me. But for most of my guns I want them to shoot straight out of the box or I don't want it.

My theory is that it's impossible for any sxs gun to center all loads. It's gotta be regulated for a load appropriate for the gauge, but I have owned several that wouldn't center anything. That's a result of lousy construction.

Having shot and patterned over 150 damascus and steel barrels over the last 25 years I have found that well over 95% of the old guns (80 to 150 years old) are well regulated. I have also learned from extensive personal experience that when removing pitting from the bores and or opening chokes, it is best to do it starting at the breach end. Many gunsmiths use reamers to open the chokes from the muzzle. I have seen this to sometimes change P.O.I in an undesirable way. I have never run into that problem while working from the breach end and out towards the muzzle.

Correct, the proper method is to work from the breech end, bushing your drive rod and reamers is good insurance as well.

If they aren’t using some sort of piloted tooling, it doesn’t matter what end of the barrel the so called “gunsmith” is working from, they’ll F it up more often than not.
