Hi new here , im wanting to build a new target gun . I only shoot 100 - 300 yards , but im looking to go with a 243 , 7 mm 08 , or some kind of 6 mm. I have pictured a mod 10 action, with a straight taper barrel in a richards micro fit marksman style stock. Thay say on the website thay inlet for savage 10. But iv been told on mod 10 that there is a difference in screw spacing from older ones and newer ones. Or are all mod 10s the same.
