Plugging vent hole

[eggwelder]

Posted this on another forum, bets advice i got was to bend the barrel. Goes against my grain.
Have my first build from 2015, and it has slight runout and shoots right and maybe a little low. I want to adjust the breech plug and turn the barrel about three flats. I`m not really concerned with filling the sight dovetail slots, and the barrel lugs are soldered on,  so easy to move.
What i will need to do is plug the vent hole, or cut it off and rebreech. I also have no issued doing that. I`Mgetting pretty good at it. I will have to shorten the stock. But i made that too, so no real issue there.
Advice?

Make a vent liner without the hole. Reps each what you have with that.

This is what i was thinking

I would recrown the muzzle first and make sure its square to bore.

      Man, I know you said that bending the barrel goes against your grain (can't fathom why) but that sure is the best and simplest solution to your problem.  Doing what you suggest will be a lot of unnecessary work to end up with a clobbered up mess.   Bending can be done very precisely using a big C clamp or an arbor press if you have access.  Gunsmiths have been bending barrels for years with good success.  It usually does not take much to achieve the desired result.  You will not be able to see the bend as it will be so slight, besides how do you know that your barrel isn't already bent and you would be straightening it...Make your life simple.

Bend the barrel , easy peasy.

You already said that it is a Japanese barrel that you don't mind having the dovetails or labeling moved by re-breeching and turning the barrel a couple of flats.  Bending is easier and cleaner looking than doing all that.  As Ron said it might already be bent.

Rich has not been a member of the Gemmer gun club long enough to know this.  The old range had a hole in one of the covered firing line posts that was used to bend barrels Sure made an easy job,  Right there at the range you could bend and test.

 Can you change the point of impact by altering the muzzle of the barrel of a rifle, like you can on a smoothbore? If so, this would be the cheapest, and easiest, fix.

Taylor tested the Bess, removed the barrel and whacked it, replaced the barrel, tested, removed & another whack on a large aspen tree, then replaced the barrel & tested - perfect!

I was referring to reducing one side of the muzzle to adjust the windage, like doubles are regulated.

There's only one way to find out for sure......

Bending the barrel is waaaaaay easier than all the steps you mentioned.  Just bend it.

Guys,

Here is a tutorial on this subject.

However, this does work a lot better with wrought iron than with modern materials.

 Something else that could be the problem is the barrel crown, or damage to it. I got a gun some years ago in a trade, and took it to the range to see if it was a shooter. It shot about a foot to the right, so I hammered the front sight over, and got it on the target, but the sight was hanging on the edge of the barrel flat. After I got it home, and started the cleaning process I notice the muzzle had a ding in it that created a small bulge in the crown. I took it out to the shop, and not wanting to waste a lot of time on a gun I was going to trade off anyway, chucked up a larger than bore round stone in my drill, and gave the crown a trueing up. A chunk of fine Emory paper and my thumb smoothed out the sharp corners, and she was ready for another trip to the range. Mission accomplished, after a couple of shots just to be sure, I moved the sight back to the center of the barrel and eventually sent her to a new home.
