Quickly and easily align the bore of your .338 Winchester rifle with your optic or adjustable sights using this In-Chamber Laser Boresight from P2M Boresights. Place the boresight in the chamber and adjust your sights or optic to the point where the laser meets a target. You don't need to spend any ammo for the process, and will probably use fewer rounds when it's time to zero because you're already roughly aligned. The red Class IIIA laser is powered by two AG5 or three AG3 batteries.
