Can you fill me in on that .211?
This bullet is .258 in diam, right? so the outside edge of the black rings should be .258.
In order to have a .211 you should have about 3/4 of a bullet width between the center - center of the farthest shots.
Working off the screen shot, it just seems like the farthest left and farthest right shots are father apart; there seems to be more like 1.5 bullet widths between their centers, than 3/4....??

thanks
