I've used Remington mag springs in several Winchesters. The standard magnum M700 spring just takes a few licks with a fine file to make it fit a M70. Basically, each end needs to be a little narrower to fit the follower and floor plate. You could also use a Dremel I suppose.
But...I never had a problem with the original weak feeling Win spring, it just makes me feel better to have the heavier spring.

I cannabilized a spring out of an FN Mauser I have just to test things out, and it improved the feeding in my 375 - lots better even super fast bolt work - as fast as I could operate it. I didn't try it upside down or sideways.
