Once you know what caliber and load you are shooting simply look through the chart to determine which one of the eight ballistic groups (A, B, C, D, E, F, G, H) match with your particular load and caliber. For Muzzleloaders, we have worked with PowerBelt® Bullets to incorporate ballistic data into two ballistic groups (I and J).
