I just finished reading JB's article in Gun's regarding "Bore Sighters", and I have a question for the masses in general, and JB in particular.
I am comfortable with the ones with an arbor that fits in the barrel, but I have never figured out how to get the magnetic ones centered and precisely vertical. I level the rifle front to back and side to side in the rest, but then just eyeball mounting the collimator. I am not satisfied with that arrangement.
How do you guys set them up, get the correct height above the bore, centered, and vertical?
Regards,
GW
