EXPERIMENTAL STUDY IGNITION OF THE 75-MM PACK HOWITZER

Abstract

A number of types of charge were tested for the 75 mm Pack Howitzer. Of these, four gave results apparently better than obtained with the present type of charge. In three of these a quick powder was used for the base section and a slower powder for the increment. In the other type, potassium nitrate was incorporated in the powder. A study of these and the previous results indicated rather conclusively that smaller dispersions in velocity are obtained with the broad banded EI projectile (band diameter .303 inches) than with the narrow banded Mk I projectile (band diameter .301 inches) and that four of the types of charge tested in these experiments seem distinctly better than the type in service use. Suggestions are made for further experiments.
