I had a M70 one made before I started getting into Tikkas and getting rid of my M70s. I had a 300WM that I had not shot in over a decade but that I recalled being my only M70 that was a really good shooter. I threw a SWFA 3-15 on it yesterday and put a box through it. I certainly did not shoot it as well as my lighter calibers but it shot pretty well. Plan to start messing with it over new years and see if I can get the RS fitted on it. Guessing I will at least need to bed it and likely do some other fitting.
I will for sure at a backfire recoil pad. Interested to see how it will work out.
