I've jug choked a couple of guns and it does indeed work very well. Old V.M. Starr from the muzzle loading era wrote a small article on how to do it - he had won many turkey shoots with his muzzle loader over modern guns. His method was to remove the metal starting 8 inches back for 6 inches and leaving the last 2 inches alone. This allowed the shot enough time to expand before coming back to bore size. It also allowed loading a muzzle loading shotgun without trying to fit a bore size wad in a smaller hole. In a 10 or 12ga IC is .010 constriction, in a 16ga .007, and a 20ga .006. So we may need a bit more in the 8ga, say .013. You would have to remove .0065 per side, and if one thinks that would make a barrel unsafe then don't do it. Maybe if your barrels are that thin to start with you shouldn't be shooting it in the first place - but that's JMHO. If you want to do it yourself you'll first need a inside mike to measure inside barrel diameter and a adjustable reamer that adjusts from the end by turning in a screw, not one by turning two nuts. Then you'll have to attach a long " T" handle to the reamer to reach in from the breech. You'll also have to make up a tool to reach in from the muzzle to adjust the reamer. The reamer is put in place, then it's tightened against the bore, turned a couple of times, loosened, removed and cleaned, and do the process all over again. It can only be tightened a thou or two each time so it becomes fairly time consuming. And you have to go in and check with the mic every other time or so. Unless you're shooting a British gun or one that's been honed many times, most good old American made SxS's have more than enough wall to remove 7 or .008 from a side. Most smiths aren't going to invest $120 for a reamer to do one or two guns. Does it work - yes. Is it safe - yes. Will you have to do it yourself - probably. Good luck.
