Can anyone tell me the rate of twist in a Winchester Model 70 Westerner (post '64) in .223?

I know how to do it myself but don't have the rifle here to do it.:redface:

Thanks guys!
 
I'm leaning towards 1:14. Interestingly the Lyman 46th manual that lists barrel twists in the appendix shows M-70 data for the .222, .225, and .22-250 as being 1:14, however .223 data is absent. It does seem unlikely that Winchester would produce a different barrel for the .223.
 
Geez, I'm not seeing anything about a 'Westerner' other than they were made starting in 1982 when the Winchester name was owned by US Repeating Arms. However, .223 barrels are usually 1 in 12.
 
The Westerner was manufactured in '63-64. I seem to recall that is was reintroduced sometime during the '80's, but I don't recall what chamberings it had been available in, and I do not see a Westerner other than the '63-'64 versions listed in the current Blue Book.

The .223 was chambered in: Featherweight, Classic Featherweight, Featherweight Win-Tuff, all Lightweight models, Sporter ('89-'93), DBM ('93 only), Classic Stainless, Coyote models except the Lite, Classic SM ('93), Varmint ('64-'93), and HBV ('93-'99).

I have that same manual and found that odd as well Boomer. Winchester did make some 223's that were 1 in 9" as well but I doubt this is one of them. I was leaning towards 1 in 14" also for the same reason that you mentioned above...
