General M712 projectiles that have been unpacked but not fired will be repacked within 30 days and returned to battalion ammunition section for further disposition. Long exposure of the M712 projectile to sunlight and other elements may cause it to fail. Code and time switch settings made during preparation need not be reset. An M712 projectile that has been unloaded from a weapon as result of a misfire or checkfire will be repacked as described below. b. Repacking M712 Projectile NOTE An M712 projectile which has been rammed and extracted from a cold cannon tube maybe reused. 1 2 3 Wipe all loose dirt and moisture from M712 projectile (1). Locate original container (2). If container has become unserviceable, replace container. If original container cannot be found or has been replaced for unserviceability, make sure that markings on replacement container match markings on M712 projectile (1). If markings do not match, return container to battalion ammunition section for remarking. Install M712 projectile (1) into container (2) as follows. (a) (b) (c) (d) (e) (f) (9) (h) Check red decals, stenciling, or stamping (if present) at nose end of container (2) halves to assure cover (3) and body (4) match.
