Sailormilan2 Posted January 31, 2010 Report Share Posted January 31, 2010 I have a 1909 Peruvian Mauser(large ring, small ring threads) that I want to change the barrel on. I know Remington 700 barrel threads will clean up just fine when rethreaded to Mauser small ring thread size. How about Winchester and Ruger threads? Will they clean up too?

Spiris Posted February 1, 2010 Report Share Posted February 1, 2010 Here's a list of dimensional action threads from Cast Boolits site. I cannot guarantee just how accurate it is. I do know that Remington's 1.060 is correct and have used them to rebarrel Turk Mausers. Action threads length Receiver OD? other Mauser lrg. Ring 1.1x12 1.41” Mauser sm.

tinkerfive Posted February 2, 2010 Report Share Posted February 2, 2010 This question came up several years ago and one member said that he'd done it several times. First off you'd want to turn 1.0 down to .98 so you'd loose the top of the 'V' on the major diameter of the 1X16. I wish that I knew what that minor diameter would be. Rest assured that it doesn't run close to the .88 for the .98X12 of the Mauser. So when you are done your OD on your barrel is kind of choppy where the 16 TPI and 12 TPI cross but the minor diameter should be a nice clean 12 TPI. The load bearing surface is somewhere between the major and minor diameters anyway because the major diameters of the male and minor diameter of the female threads are the thinnest parts of the thread. I'll try to put it another way. If the 'choppy' part of the male barrel thread doesn't exceed more than 1/4 of the thread height it probably makes little difference. You do the math and decide for yourself. It's something that I've considered doing but haven't done yet. I wish that I could remember who the member was that had done several. Truth be told I'd play it safe and set the shoulder back as much as possible to cut into virgin barrel. If half or more ofthe length of the thread shank length could be into virgin barrel that would be better. You have to weigh that against how deep you can extend the chamber safely.

The Remington 700 is 1 1/16"(1.062) X 16 and will clean up just fine for small ring mausers. Neither Winchester or Ruger will work for small ring mauser. Here's a 338-06 on a K-Kale action. The barrel is an ER Shaw remington contour and remington shank that I rethreaded for small ring mauser. I'm getting ready to do another in 22-250 0n a 1936 mexican action http://www.sporterizing.com/index.php?showtopic=6480 You may recall there was a big controversy several years ago over whether these modifications were suitable for magnum cartridges.

weaver77 Posted February 3, 2010 Report Share Posted February 3, 2010 The shanks on most of the ruger barrels are long enough and have a large enough O.D. to thread to large or small ring and still have enough shank left to look good and fit in barrel vise.

tinkerfive Posted February 4, 2010 Report Share Posted February 4, 2010 was it clark? for some reason his name sticks out... Clark's name sticks out because he is the boards resident master of destructive testing. I don't think that he is the one. Well I was curious so I had to do the math to see how it would work out. Using a 1" 16tpi bolt reference, my son ( the engineer ) looked up and found that the minor diameter spec was .924. As the 12tpi threads went around and crisscrossed the 16tpi threads the OD of the barrel would vary from .98 down to .924 when the 12tpi crest met the 16tpi valley. At those points rather than a .05 tall/thick thread, the thread would only be .022 tall. I imagine that this would follow a spiral pattern. I think that you'd have to see one done to evaluate for yourself. I hope my math is correct Tinker Quote Link to comment Share on other sites More sharing options...

So can anyone weigh in on the controversy of whether a k.kale with small ring shank barrel is suitable for magnum cartridges? Quote Link to comment Share on other sites More sharing options...

donmarkey Posted January 2, 2011 Report Share Posted January 2, 2011 I personally wouldn't do it. Mausers have a coarse thread so there wouldn't be a very thick chamber wall left at the minimum thread diameter. Don Quote Link to comment Share on other sites More sharing options...
psuedoperson Posted January 4, 2011 Report Share Posted January 4, 2011 That makes sense to me.So would you say that they are safe for most non magnum rounds? Quote Link to comment Share on other sites More sharing options...
ken98k Posted January 4, 2011 Report Share Posted January 4, 2011 That makes sense to me.So would you say that they are safe for most non magnum rounds? There are millions of them in 8mm mauser so I would definately say yes to non-magnum. there are at least 2 members here that have built magnums on small ring turks and swear by them.
