RE: Laser Bore Sighting
A friend of mine has one and we've bore sighted a couple of my slug guns and my muzzleloader. Seemed to work fine getting you close. We bore sighted, set a target up at 25 yards and went from there. Saves you a few bucks in the long run with the price of good ammo these days. Sorry I don't recall the brand but it will work up to 50 caliber then he bought the rubber spacers for up to 12 gauge shotguns.
