Don't waste yout time - SSI Sight-Rite Deluxe Laser Bore Sighter for Pistols, Shotguns and Rifles

I bought this thinking it would be useful. I sighted in a brand new Savage .17 HMR and was over 18" high at 25 yds. I had to adjust the laser to center by using a rifle I already had sighted in. Pretty bad when you have to use a scope to sight in your bore sighter.
Pros: price
Cons: everything else about it
