Between my father and I, we own factory M70s in 300WM’s and 338WMs, there isn't much difference in load tuned accuracy. It’s a spread from early 70’s, mid 80’s, and a later model CRF. 2/4 are super grade for the wood, not that it matters. They are all 26” long tube factory sporters and 1.5 MOA at very-very best rifles with ammo work. I stress the work or effort and the repeatability isn’t like other rifles I favor. Perhaps more on me. It’s not a rip on Winchester, its reality. Everything is more precise on the internet. Plugging anything into these animals exhibits allot of variation.
On a side note, there is internal ballistic efficiency that becomes appreciated with the 338WM against the parent trio for Win. Bullet mass and exit velocity vs pressure ignoring BC.
I don’t have any practical love with CRF actions. Anything custom I have is DM based and PF is preferred. The real difference is in the extractor, ejector, lockup, the non-circumference external receiver geometry, and recoil lug. There are multiples in the previous statement that define common actions, some are a Win (yes pun). From a speed and reliability standpoint, function vs time must be considered. NO one is demanding CRF, other then parent actions that have it.
Some of these are Winchester wins and some of it is the ironic nature of starting with less more easily making it more (M700). And I love old Winchesters. The last parallel is Savage. Its easy to correct for a factory bolt face with floating lugs. It’s a horrible action to work.
Very seldom can I not make a M-70 CRF shoot sub MOA. Between bedding, trigger and occasionally some crown work.
