I just finished resizing my Star Line 44 Mag. brass that I shoot in a FA revolver. I shoot IHMSA silhouette with it and when I measured the cases the case length varies .004 inches. I know its a very SMALL amount but do you think it would make a difference in accuracy. Remember the shoot off targets are chickens set at 200 meters. Lot of work trimming 500 cases for .004 inch difference.
