if you have - or can borrow - a bore sighter, check the point of aim on the present scope, install a new one making sure that the base and rings are tight, and adjust the new scope to the same point of aim while leaving the bore sighter installed on the rifle. shoot it at short range to see if it's on, and then go hunting. i agree with the man who said that the 2" group could become 5" the next time out. you'll be flogging yourself if you miss a big one because of it!
i'd hate to see that happen to you.
good hunting, good shooting,
