The best thing to do, what i do, is put the rifle in a rest. It'll take you, the shooter, out of the equation. The slightest difference in your position can through you off. Also ive never had anyone else zero my weapons, everyone shoots different so what is good for my buddy may not and probably isnt good for me.

When i bought my savage .22-250 the scope was already mounted and supposedly boresighted. I couldnt hit anything, someone had tightened down the screws on one side then went to the other. The rings were touching on one side but there was an 1/8 in gap on the other.
Yes, I forgot to add you must use a bench rest. Also, my scope mount was loose and had to be re-tightened at some point.
