I bought a win M-70, and it wouldn't put 5 shots in a six inch circle at 80 yards!
Took the action out of the stock and about had a heart attack! I don't know how many people had tried to "fix" this rifle,but the inside of the stock was ruined! The barrel channel had been filled with fiber glass resin, and the recoil lug looked like it had been bedded with bondo, which most was broke out! It was beyond repair! So I ordered a Boyd's TH stock in pepper laminate, and although it was supposed to be cut for a varmint barrel I still took two days opening it up enough for the barrel to fit! I then ground out some wood in the recoil lug,and on the flat behind it, and just ahead of the lug, drilled it for an aluminum pillar, and bedded the whole ares with Devcon 10110 epoxy steel!(lets see that chip out!)
Now at 200 yards it will shoot half MOA with handloads, and MOA with factory
(if you can find it!). I also refinished it with 15 coats of Tru-Oil. I also installed a rifle basix trigger as the factory trigger had been "worked on", and was set at 7 pounds! Anything less and it was unsafe! It is now set at one pound as I like light triggers. I like it!!

I also have a CZ452 .22 rimfire I "had" to tinker with! Restocked into a Boyd's TH vaarmint stock I got as a production over run, for about half price. Installed an AS adjustable sear, which with the trigger spring changed gives me a 6 OZ trigger with no creep or overtravel(I use this for bench rest shooting only!).I also installed a action pillar, and although I didn't bed the action, it will shoot .2" to .4" and some are tighter!
I also put 20 coats of Tru-Oil on the stock as the factory finish had no color! It is a fun little rifle to shoot!
