Some people can just shoot a little better than others thats all. In the general discussion when I left the review on the MPA30 CHEAPO carbine with a 2.5 shotgun scope on it, one of the guys there shot a 3'' 5 shot group at 100yds. with the thing. Out of 5 guys there he out shot everybody with all the rifles there his and ours! One guy had a Armalite AR15 20" A2 stainless barrel there and this guy was doing sub 2'' with 55gr. WW white box and some surplus ball with open . On average his groups were half the size of everybody elses there. I won't tell ya what his groups were with his Remy 700 in 22-250, I was very impressed though.
