Major Crimes Posted November 17, 2019 Share Posted November 17, 2019 This should give you the answer. https://www.uberti-usa.com/uberti-posse-blog/the-official-uberti-usa-rate-of-twist-chart Link to comment Share on other sites More sharing options...
Griff Posted November 17, 2019 Share Posted November 17, 2019 Thread pitch would be the outside of the barrel, where it screws into the receiver. Rate of twist is the inside impacting the travel of the bullet thru bore and the spin imparted to the bullet. As I understand the question, that link doesn't give the answer.

Palouse Posted November 17, 2019 Share Posted November 17, 2019 Old Uberti, or new? Just like the data on the link above does not apply to pre-2004 bore dimensions, Uberti may have changed barrel shank thread dimensions at some point, or multiple times. If you are thinking about rebarelling an action, better to measure what you have, as a start. Link to comment Share on other sites More sharing options...
Jailhouse Jim, SASS #13104 Posted November 17, 2019 Author Share Posted November 17, 2019 My current round barrel at the chamber end is .798 OD with 16 tpi with no factory parts available. If it was a smidgen thicker at the muzzle (.675), I would simply put a liner in it. I'm looking for a compatible barrel on the used market in 38WCF or 44WCF. So far I have found a Navy Arms that is .920 OD with 16 tpi that would require minor machining. Winchester is close in OD but is 20 tpi. I may have to go new but it doesn't hurt to explore other options. Link to comment Share on other sites More sharing options...

Rebore??? Now that could be a possibility, although might be more economical to get a new barrel threaded in the end. I'll need to research doing a rebore.

I'll need to research doing a rebore. Rebore is usually about the same price or less than a re-line and a lot less than relining a small dia round barrel for sure. It will be less than a worked up new barrel blank, too. Particularly if you have to do the taper to match, the dovetails and blueing. I have a barrel guy that has done several re-bores for me. Let me know if you need his info. Link to comment Share on other sites More sharing options...
