(Пиччоне Доминик А. Сравнительный баллистический эффект 20 мм бронебойного M65 и 20 мм бронебойного M75 снарядов по бронеплитам из гомогенной стальной брони). — Technical report. Watertown Arsenal. 1960. – 24 p. At the request of the Ordnance Tank-Automotive Command, Watertown Arsenal Laboratories have conducted a series of ballistic tests to determine the terminal ballistic performance of the 20MM АР M75 and 20MM АР M95 projectiles against rolled homogeneous armor plate of specification hardness. Specific information was desired on the performance of both projectiles against overmatching armor at low obliquities and undermatching armor at high obliquities. Ballistic testing was conducted to determine the relative performance of the 20 mm АР M75 and M95 projectiles against rolled homogeneous steel armor of specification hardness. Neither type projectile possessed the metallurgical structure or hardness pattern conducive to optimum ballistic performance. The results obtained indicated that on an energy basis the 20 mm АР M75 is approximately 36% superior to the 20 mm АР M95 projectile in the 0-20° obliquity range, and approximately 12% superior in the 45-60° obliquity range.
