注释如下
The propellant was in six bags for both full and reduced charges. Primer patch was at one end, quilted to ensure even distribution, and usually colored red. The other end had a handling strap. Bags were transferred from hoist to loading tray three bags at a time and then all six bags were rammed into the breech with a single stroke. During the 1980s reactivations, some experiments were performed using five bag loads. The D839 propellant grain used for full charges issued for this gun was 2 inches long (5.08 cm), 1 inch in diameter (2.54 cm) and had seven perforations, each 0.060 inches in diameter (0.152 cm) with a web thickness range of 0.193 to 0.197 inches (0.490 to 0.500 cm) between the perforations and the grain diameter. Propellant bags were made from raw silk, although rayon was introduced during the 1980 activations.
