Will a magnum face bolt from a new model 70 work in a Pre 64 Win 70 receiver?

It has to be headspaced, and fitted properly. They are not plug-n-play. That is if they are still made to the same print, and you would need a Model 70 Classic, with the claw type extractor.

Thanks Babun, the reason for my asking is the bolt cycles fine in my pre 64 70 in 243. It's a tad tight when closing the bolt the last 1/4" but the trigger and safety work fine.

A long time ago I tried fitting three pre64 M70 bolts (they all had a standard length then) in different pre64 M70 rifles; and they were a tight fit and wouldn't close so I stopped at that point. This came about when I read an article by James Carmichael where pre64 M70 bolts was inadvertently switched during cleaning while on a safari. The result was that one bolt broke off when one of the rifles was fired. It makes you wonder sometimes - Yea "Plug and Play" it is not.

I've purposely tried different bolts for feel fit in win 70 rifles and NO, not plug and play.
I always make sure that the ser# of the gun is on he bolt of a gun, especially Win 70's.
Even if a bolt has a good feel fit do not attempt test firing until it's has the headspace checked.
