Gunsmithing Recontour barrel

[ForeverZ01]

If I have a M24 contour barrel and want to take it down to say a sendero or heavy sporter what would be the affect on accuracy.

 

[Supersubes]

None whatsoever. Is this a blank or a finished barrel?

 

[ForeverZ01]

It's finished and on an action

Who made the barrel? Cut or button? I suggest you contact the manufacturer and ask them. Iirc, Kreiger would only recontour down one size or two and when I did so it was a blank not a finished barrel.

Bartlein barrel

 

[Supersubes]

Ive had barrels recontoured, and always send them to the maker for the work. Usually about $50 plus shipping. Never done that for a finished barrel though.

Bartlein will do an unchambered barrel for a nominal fee.

 

[ForeverZ01]

I appreciate the info

It shouldn't be a problem unless it has button rifling which creates stress in the metal. Bartlein does cut rifling.

They'll also do a chambered one. I had them turn a #3 to a 2B that was already chambered.

I've recontoured barrels before with no effect on accuracy. One of them was a Bartlein in a 6.5 creedmoor that I built and had no effect that I could tell

If you can have it done for $50.....jump on it. It's not worth the clean up for that price.

I called bartlein and they said they don't recontour finished barrels.

I've re-contoured barrels on my lathe. It's time consuming and a PITA. If you can get a barrel manufacturer to do it for $50.00, by all means, do so. The best advice I can offer is either live with what you've got, or buy a new one with the contour you want.

They did one for me. The only thing they said about it was that it would need to be recrowned afterward, which was no problem. Maybe they've changed their policy but they did it two years ago.

Ditto. I've done it a couple times. I started using a belt sander to grind everything smooth after it was turned.
