I will be using a muzzle laser to check my point of impact before going to the range. It will be used on both the O&U and SxS 30-06 doubles that I have. Lasers don't bend, so the muzzle version will be the only one that will work with guns that flex the barrels for regulation.

On the O&U I will sight the scope to the fixed top barrel using the laser first. I will try to regulate the bottom barrel to the top barrel's point of impact using the laser and barrel adjustments. Hopefully the horizontal point of impact is in line wth the fixed top barrel.

I will repeat this process with the SxS using the left fixed barrel as my starting point. Hopefully the verical point of impact is in line wth the fixed left barrel.
