The very rear (what you are calling the tang) of the action where the safety is at is supposed to be free floated. If it were to touch you would lose accuracy. And there is a specific sequence to torquing the action screws if your stock has the wedge insert for the recoil lug, which my model 10PC has. I get the impression that the wedge was removed on later accustocks.
+1 The rear tang should not be touching. As for accuracy, I'd surprised if the right powder/bullet combo will not do just as well as the 70's.
