RE: laser bore sighting
I have the SSI and it works great. I set up the target at the end of the hall in my house and steadied the rifle on my kitchen table. When I mounted a new scope on my ABOLT, I used the SSI to bore sight and was within 2 inched of being perfect at 100 yards, with no windage adjustment neccessary whatsoever. The only issue I have with it is that I wish it came with 50 caliber o-rings so you could use it with a muzzleloader. If you were industrious you could probably find them at a hardware store...
Good luck-
