Description
Booster M22 is used in conjunction with PD fuze M57, some in stock being assembled to 105mm howitzer chemical projectiles. In external contour, this booster is similar to booster M21A4. Booster M22 differs from booster M21A4 in that it is not bore safe, because of omission of the rotor. Booster M22 has a solid body, except for a drilled hole through the center. A detonator assembly, containing two pellets (one lead azide and the other tetryl), seats in the hole in the booster body. The booster charge is contained in a booster cup screwed on the base end of the booster.
