Abstract:

An investigation was initiated to determine whether the readily available standard M107 projectile could be used to satisfy the 18,000-meter maximum range requirement for the M109 weapon. The range dispersion of the ammunition was excellent. Range Probable Errors of only 0.2 or better at 18,400 meters maximum range were achieved in almost every case. Even in the worn tube, a volley of 20 rounds produced a low-range dispersion. Complete data pertaining to propelling charge description, lethality advantages of the M107 projectile compared with the M470 projectile, and ballistic test data are given in this report. Author
