Same here, be rebarreling for target shooting long range.

If yours was made in Conn it is most likely 1"-16. The overwhelming percentage of all Winchester M70's (and clones, both domestic and Chinese) are 1"-16 tpi. FN made guns and possibly late New Haven ones MAY be 1.062"-28. The WSSM calibers are the finer pitch. I have also seen FN SPR type guns with both thread pitches. Sure fire way to tell is yank the barrel.

Yeah, had in my budget a barrel this month, but looks like next month,

It could also be 1"x28.
The easiest way to tell is to unscrew the barrel and look.
The difference between 16tpi and 28tpi is quite obvious.

I haven't run across one of those yet. Which version? I have a WSSM that's 24TPI. That was a surprise when I unscrewed that one about 6-8 years ago. There's always something to keep up with!

But the Control Round Feed model requires that an extractor cut be made on the breech of the barrel and the only way to accurately align this extractor cut is by the barrel being installed on the rifle and the extractor cut groove being marked, the barrel being pulled back off the action and then milling the extractor cut. Therefore it is recommended that the Winchester Model 70 pre-fit be installed by a qualified gunsmith.

Lynn, would that also apply to most Model 98 and Model 24/47 Mauser actions ?

The 98 doesn't usually get an extractor cut if my memory is correct. If your using a Mauser action that has the protruding ring or sleeve on the end of the action and you grind it or file it off those sometimes need a extraction cut.

No.
Mauser 98's have a flat breech face that seats against the receiver.
There is no cut for the extractor as all of the barrel is forward of the extractor.

A model 70 controlled feed has a coned breech which requires an extractor cut as most of the cone is behind the extractor.

[Flouncer]

Thanks both of you. I have asked before but it has been a while.

[TRAP55]

The 24/47 and M48 have the safety breech cut.

There is no question that unscrewing the barrel and measuring the thread pitch will reveal what you have.

LOL

Only if one can count, and recognize 1" on a ruler.

Don't go taking things for granted.
This is calguns.
