NOTE
(1) Primer M82 is the only authorized primer to be used in the M109A2/M109A3/M109A4 M185
or M109A5 M284 cannon assemblies.
(2) The M119A2 charge 7 (Red Bag) is equivalent to the M119A1 charge 8. Refer to firing tables
for small differences in velocity which affect range.
(3) The M203/M203A1 charges are to be fired in the M109A5 M284 cannon only.
(4) The M864 will be fired with the M203 series charge only in the M109A5 M284 cannon. The
M864 will be fired to achieve ranges beyond the capabilities of the M483A1 projectile or when
the M483A1 is not available. M203 series charge 8 is not equivalent to M119A1 charge 8.
(5) M116 and M116B1 restricted from overhead fire with zone 7 of M4A1/M4A2 charges due to
possible base plate separation, creating downrange safety hazard.
(6) M825 projectiles (manufactured Jan 85 - May 86) fired at temperatures above 110
°
F (43
°
C)
(WP liquified) have resulted in flight instability and short rounds. This instability does not
occur below 110
°
F (43
°
C) (WP solid). This restriction does not apply to M825A1 projectile.
(7) M825 projectiles are restricted to firing below 950 mils elevation with the M203 series charge.
Firing of this combination at elevations exceeding 950 mils may result in short rounds. This
restriction does not apply to M825A1 projectile.
(8) Do not fire the M549/M549A1 projectiles if the obturating band is missing or broken. If band is
displaced and can be repositioned and remain in the groove, the projectile can be fired. The
M549A1 projectile can be fired with the M203 series charge and M232 charge 5 but the M549
projectile must never be fired with the M203 series charge or M232 charge 5.
(9) Do not load or fire M231 charges with M232 charges. Critical malfunction could result. M231
and M232 are authorized for the M284 cannon only.
