[QUOTE="MagnumManiac, post: 2166682, member: 10755"] Did a side by side test with .001”, .002”, .003”, .004”, .006” & .008” induced runout. At 600 no discernible difference in average group size could be seen. Gave all my concentricity tools away and never looked at it again. Seen a bigger difference in aggregate from a change in CBTO in a bullet batch I didn’t measure than from runout. How does a bullet that may be .007” off centre fit into a leade/throat that is .0005”-.001” larger than bullet diameter WITHOUT being straightened somewhat? Does it stay at .007” off centre? Have you ever measured before and after seating said bullet? Concentricity is the least of my concerns when making precision ammo. Concentric necks is a whole ‘nuther ball game. Cheers. [/QUOTE]
