I just traded for a (1974) 30-06 Winchester Bolt Action Rifle Model 70, The Gentleman in his 70' bought this rifle new in 1974 with the intent of going out of state Deer Hunting,but never went.The Rifle is like brand new ,it's never been shot,he even give me all the papers that came with the rifle.
My Question's , I have been told from 1965 till 1980 they had problems with Quality control from the factory ,I know after the 1964 year they changed their bolt design and a lot of people didn't like this ,I would like to take this rifle out of state deer hunting but if their were a lot of problem's with this rifle, I'll trade it off before I shoot it, I know there a lot of people out there that has these guns, and I like to know the Pro and con's of the design and how they shoot.

Thanks SingleShot
