As a gunsmith, I've sighted in at least a thousand rifles for others over the years and have never had anyone come back and say it was wrong for them.
At a turkey shoot, four of us used the same rifle to fire one round each and all of us hit the 1" target center on separate shooting rounds, winning 6 turkeys that day. We were shooting prone over a log at 100 yards and the rifle was a .22-250, Rem 700 ADL, 2-8X scope, shooting 55 gr, Sierra Semi-point handloads.
At another shoot, on a bet, my wife shot a perfect pinwheel with the same rifle; her one and only shot in competition, 7 months pregnant, laying on an angle, due to her belly. It wasn't a pretty scene, when other wives were asking her to teach their husbands how to shoot. Most of the guys never returned the next week, so they never held turkey shoots again.
