I have another Model 70 and found that the bolt/safety in the safe position acts the same as this one in the fire position. For what that is worth. The Mod 70 safety is a swing lever: Forward, fire. Mid: safe/bolt removal. Rear: safe. I am looking at my 1981 Sporting Rifle Take Down and Assembly Guide by J.B. Wood. I do not see any way that this rifle which is virtually new and 7MM Mauser by the way, could become jammed. (Ser no:G1539XXX). I did fire a few rounds of commercial ammo for sight in..four rounds for the sight in, 6 rounds for fun. I will remove the scope/bases and start over. Thanks for the response.
