M1 Propellant With Lead Foil Sheets

Use:

This propelling charge is a Zone 7 red bag charge for firing in 155mm Howitzers containing M185 and M199 cannon tubes.

Description:

The M119A2 Propelling Charge is a single increment red bag charge which contains a base igniter pad with 4 ounces CBI powder and a center spot of 0.5 ounces of black powder. The charge is approximately 29 inches long by 6 inches in diameter and contains 20,9 pounds of M6 propellant. The forward end of the charge has a 3 ounces lead foil liner and four pockets sewn longitudinally to the circumference, Each of the four pockets contains 4 ounces of potassium sulfate to act as a flash reducer.

Functioning:

Upon firing the weapon, a flash from the primer ignites the CBI powder in the base igniter pad which ignites the black powder spot, The burning of the CBI and black powder spot in turn ignites the propellant, The burning pro-pellant generates rapidly expanding gases which propel the projectile through the barrel and up to the velocity required to reach the target, The flash reducer functions to reduce blast overpressure and flash at the muzzle of the weapon. The lead foil liner serves to prevent copper build-up (coppering) in the weapon.

Difference Between Models:

The M119A2 is base ignited and does not contain a center igniter core and tube as in the case of the M119 (M119A1), Although this charge is a Zone 7 it can be used interchangeably with the M119, M119A1 Zone 8 charges and like these charges the Ml19A2 is to be used in the M185 and M199 gun tubes only. The M119A2 does not have the outer lacing jacket that is used to wrap the M119 and M119A1 propelling charge.

Use:

The M203 is a Zone 8 S charge designed to supplement the standard M3, M4, and M119 series charges and to provide extended range for the 155mm Howitzer M198.

Description:

The M203 Propelling Charge is a single increment, red bag charge, approximately 301/4 inches long. The charge contains approximately 26 pounds of the high energy, M30A1 pro-pellant in a cloth bag. A red cloth igniter pad containing 1 ounce of black powder is sewn to the base of the charge. A central ignition core extends through the center of the charge for almost its entire length. This ignition core consists of a nitrocellulose paper tube containing a bag of black powder which is sewn to the base igniter. A liner consisting of a cloth side impregnated with titanium dioxide and wax, and a lead side lines the forward end of the charge. Four tie straps sewn to the base of the charge run the length of the charge and are tied to the forward end of the charge, A donut shaped flash reducer is inserted under the tie straps at the forward end of' the charge. A cylindrical jacket is placed over the charge length and tightly laced. This lacing jacket serves to provide necessary rigidity and structural stability

Functioning:

The flash from the black powder in percussion primer M82 ignites the igniter pad at the base of the charge. The burning igniter pad in turn ignites the black powder in the igniter core to spread ignition to the propelling charge. Rapidly expanding gases from the burning charge propel the projectile through the barrel of the weapon with enough velocity to reach the target, The flash reducer functions to reduce blast overpressure and flash at the muzzle of the weapon.
