60mm Mortar Blue Practice Shell WW2 U.S.
 

81. SHELL, PRACTICE, M50A2, W /FUZE, P.D., M52, 60-MM MORTARS, M1 and M2, COMPLETE ROUND (fig. 59), is a practice round provided for the 60-mm mortars by adapting service items for this purpose. Components of the M50A2 Practice Round are the same as are used in the M49A2 Service Round except for the high-explosive shell filler. The M50A2 Projectile has a filler of inert material (plaster of paris and stearic acid) and a black powder pellet (0.05 lb) loaded adjacent to the booster of the M52 Fuze. The M52 Fuze is a superquick fuze and shell is functioned before penetration occurs. The black powder pellet and booster charge provide a spotting charge for observation purposes. The shell is loaded to the same weight as the service round, thereby providing for the same ballistic values.
