If you have a bore sighter, then by all means bore sight the thing. I personally take a large piece of cardboard and start them out at 13 yards and shoot for a bull. Then back up to 25 yards and again, shoot for a bull. I just work my way back to as far as I think I will shoot. That does a couple things, it checks my mounting procedures, and scope, also it gives me time to get used to the scope and the recoil of the rifle.
