Can I effectively counter rotate a canted barrel?

[peppercorn]

I have a new 629 that has a slightly canted barrel, over rotated/tightened.

My question is, can I bring it back to top dead center and be no worse for the wear?
How will this effect barrel torque?

I know I willl have to adjust for the change in sight picture, I am just wondering what the ramifications are if I rotate it myself.
Total rotation would be approx. 5 degrees, best estimate.

Thanks

Has anyone done this and,if so, do you have any advice?

If you have a truly new 629, I would recommend calling S&W and telling them the situation. This should be covered under the warranty. They will provide a shipping ticket. If it is an older one, you'll need a frame wrench.

As above you MUST have a real revolver smiths frame wrench with the correct polymer insert to fit the "N" frame along with a correct barrel insert for a barrel vise.

As to actually doing this, it likely won't work out.
When you back a barrel out you break the torque and vibration will cause the barrel to loosen and start to unscrew.
Even a slight amount of backing out is usually enough, especially in a heavy recoiling revolver like a 629.

In any case, as above, your gun will probably be covered by the S&W warranty, especially since it's an obvious factory error. Best advice is to talk to S&W.
If it's under warranty, they'll send you a shipping label so you don't have to pay shipping.

What S&W will do is actually reset the barrel and this will eliminate any problems with the barrel loosening.

I was trying to avoid sending it back, if possible.

This is exactly what I needed to know.
Thanks.

Under NO CIRCUMSTANCE should you attempt this. This is a job for S&W ONLY. Not you, not your local 'smith, not Uncle Bubba. Send it back to S&W.

Uncle Bubba was the one that had the idea in the first place.

No, I'm set on this one. I'll send it to Springfield, once I stop shooting long enough to do so.

don't be suprised if they say that it is within specs, and there is nothing they can do to it.

If you have the proper frame wrench/with insert, and the ability to use it, you could remove the barrel,use a metal punch to raise a couple of pricks on the rear of the barrel,and re-install.It might take a try or two but it will work if you can raise enough metal on the barrel shank to aquire a proper torque with the sight aligned. First choice would be send it back to S&W, second choice send it to a good 'smith. Third choice do it yourself.If you undertake this project DO NOT try to raise pin pricks on your frame. Remember,modify the cheapest parts first. Good luck, Nick

How does it shoot now?
