WHAT THE HECK?

Any one ever run into this problem? The muzzle on my RIA barrel is not perpendicular relative to the bore. The bore is true and consistent for the entire length of the barrel, but there is a noticeable cant at the muzzle when viewed from the top or bottom of the gun. When measured, one side of the barrel is 0.046875" (3/64") shorter than its' opposite side. I haven't had a chance to put any rounds through it, so I'm not sure what effect it will have on accuracy, but with the base of the bullet not making contact evenly with the rifling as it exits the muzzle, it can't be good. My question is should I leave it as is, have a gunsmith recrown the barrel, or have ARMSCOR replace it. Any/all suggestions are greatly appreciated!

The muzzle should be cut square. Anything less is less than adequate. Simple. A "match cut crown" is a bonus, but it must be square, in any case.

Take some pictures and get with Armscor to see what they say first.

A competent gunsmith with a lathe could fix that in a few minutes; it's a pretty simple job.

I would go that route, rather than going through the hassle of trying to get the barrel replaced for another, that may or may not be correct.

A crown that is not square will definitely affect accuracy, as much or more than any other feature of the barrel.

Ri does not seem to have the barrels atm, so just get it crowned local

Thanks for the input everyone. I talked to a local smith, and he said that he can take care of it. He showed me some of his work, and from what I saw, it shouldn't be a problem. Also very reasonable rates.

Another option is to spend a little money on manual target crown reamers, and do it yourself. This however, requires a bit of patience, and if you only plan to do it once, then it isn't really worth it.

This is good advice for a lot of gun guys with some DIY skills. In general I find that unless the tooling is really expensive I would rather spend my money to acquire the tool and then do it myself.
