i would buy a bore sight. they are nice later so you know if your scope is off .now, do you need one, no, if you sight in like i do.you need 2 people to do this. here we go, put your target at 10 yards. shoot 1 shot off bags on bench.NOW, have your buddy turn your sights to the HOLE where you shot while you are still holding the sights on EXACT BULLS EYE of target you were shooting at.use a large piece of cardboard and a very small target. i like those little red stickers about 1/2 dia.targets with black diamond in center and cross hairs in it. secret is you MUST hold still and keep your sights on the same point you aimed at and let buddy turn sights to the HOLE where you hit.do this and you should be fine on next shot.take care.
