A copper-plated hollow-point loaded in a .44 Magnum, for example, with an original weight of 240 grains (15.55 g) and a diameter of 0.43 inch (11 mm) might mushroom on impact to form a rough circle with a diameter of 0.70 inches (18 mm) and a final weight of 239 grains (15.48 g).
The group on the right measures about 7 mm and was fired at about 90 meters, which equals 7 mm / 90 m = 0.08 mils (0.3 in group at 100 yards, approx. 1.047′×0.3 = 0.314′). In shooting sports , a shot grouping , or simply group , is the collective pattern of projectile impacts on a target from multiple consecutive shots taken in one ...
In some instances, the powder may not have even been fully burned in guns with short barrels.
