My 2 main hunting rifles forever, have been a 1980 ADL M700 .30-06 and then a 1989 BDL M700 .338WM.
I always hunted in sleet, rain, snow and I didn't like the factory wood stocks on them, cuz of the abuse I'd put them through.
Took them to K&S Arms, Edmonton and got both actions mounted in Wildcat Composite stocks. And then have never looked back and never worried again about adverse weather.
The only failure I ever had with either was due to some small amount of rust in the bolt of the .30-06, and missed a really nice whitetail due to it.
I've since acquired a tool for stripping the bolt (I can't do the bolt on the edge of a table thing) and regularly inspect the bolt, firing pin and spring.
The Winchester M70 which I have just ordered, corrects a mistake I made a long time ago. I had a M70 Featherweight in 7x57 and sold it. Now that was a push feed model, fwiw, but I've always regretted selling that rifle.
Getting this fine new Featherweight in .270Win corrects that error, and improves on it, as I believe these new production CRF Winchesters are superior to that older M70.
And I'm not sold on the need of CRF but just think it's cool.
