In my previous review of the Wolfroad green laser boresighter, some of the comments I had doubted the suitability of the device because it wasn’t spot-on when installed. In this episode, I show how to use a bore sighter to sight in a scope, optic, or open sights.
Laser bore sighters, which fit into the muzzle of your barrel, are not 100% dead nuts center on your bore. There’s a certain amount of looseness in the tolerances, from the laser diode to the straightness of the stem, to threads of the screw on the caliber adapter. It’s normal that they’re just a few degree’s off.
But by using a little practical geometry we can get around this imprecision. By rotating the bore sighter while attached to your barrel, the laser dot traces a circle around the center of its axis; your barrel. You can either estimate the center of that circle or simply position the dot at the nadir of the curve, you can aim the vertical/elevation centerline with your barrel.
This will almost certainly get you on paper if nothing else. Once you get holes on paper you can make finer adjustments to zero your sights.
