Advanced Weapon Boresight System (AWBS) by CI Systems
Walt (at BMC Tactical) occasionally breaks out the shop’s .416 so people can shoot $7 of freedom (on New Year’s Day and 4th of July). The problem is that it is not zero’ed for distance shooting. Mainly because he’d rather have people just fire it rather than burn the ammo (and money) on dialing it in. Personally I’ve never had good luck with bore sighting (I find it easier to just put rounds on paper and start moving out and adjusting; or the two shot method).
