That is a wonderful family heirloom. The pre-64s are great rifles. Teddy, please take the time to absorb the family oral history which accompanies this rifle. Too often we realize, too late, that we should have asked more questions of our ancestors.

THIS!
TeddyFive06, that is one very nice rifle. Were it mine, it would definitely stay in the family.
The suggestion of a "hunting" stock is a good, especially if your style of hunting is a bit "hard on equipment." I suggest you keep learning about Model 70 rifles. As you learn more, you will likely come to appreciate that rifle even more. (When you mentioned your current lack of knowledge about M70's I thought "Dear Lord! This guy just had a jewel drop in his lap and hasn't a clue!)
You have already learned that bolt clearance is an issue with Pre '64's. It is much less an issue with post 64 M70's. You are also about to discover the .338 can rock you a bit. Careful ammo selection and hand loading can mitigate that a bit.
