A mortar bedding or training round has a canister filled with a heavy, dispersible filling and a sidewall that will rupture after firing of the round. The canister sleeve may be dimensioned to provide an expansion gap within the barrel, allowing the canister sidewall to partially expand upon firing, weakening it for subsequent rupture upon leaving the mortar barrel. Such a round can bed a mortar without launching a projectile to a high altitude where it might be detected.

A mortar round for firing from a mortar having a mortar barrel with a muzzle, said round comprising: (1) launching means for launching said round; (2) a seat for carrying a containment canister mounted on said launching means; (3) said containment canister mounted on said seat, said canister comprising a sleeve with a sleeve sidewall; (4) a capping means for sealing said sleeve positioned at the end of said sleeve opposite to said seat; and (5) a flowable filling having mass positioned within said sleeve wherein: (a) the mass of said filling is sufficient to effect recoil of the mortar upon firing; and (b) said sleeve sidewall has a reduced strength portion that, upon firing of the mortar, will be sufficiently weakened by said firing as to continue to contain said filling while Said sidewall is within said barrel but rupture upon leaving the muzzle of said mortar barrel thereby releasing the filling for dispersion into the surrounding space and thereby simulating the firing of a live round.
