Yesterday I fired off some 147 Blazer FMJ rounds from a certain 9mm pistol. And the 14-round group had a center that was maybe 2 inches left of the aiming point, at the 15-yard distance.
Then, same gun at same distance with same cross-wind but using 115 grain Blazer FMJ rounds. The 14-round group was dead-on in windage.
(You will notice that I am carefully not stating the actual size of the group )
So is there any reason that bullet weight, and bullet velocity, will change the group to the left? Or was I just getting warmed up and shooting straighter?
