ABSTRACT A full-caliber shell for training purposes is intended to be fired with a low charge in a large-caliber firearm, e.g. a howitzer or a gun. The shell comprises a front part made of heavy material, an effect part with a casing and a bottom unit. The effect part casing and the bottom unit are substantially made of plastic material which is highly resistant to, inter alia, high pressures. The effect part casing and the bottom unit are arranged to withstand the great stress forces which arise in connection with the firing of the shell in the howitzer when the heavy front part is to be accelerated by means of the effect part and bottom unit. The stress forces are then very pronounced, and are of the magnitude of those arising in connection with the firing of a steel shell with the corresponding charge. The heavy front part, the effect part with its charge, and the bottom part are carefully balanced in relation to each other so that they give ballistics and a weight which makes the new shell substantially equal to the steel shell which the new shell is to supersede. In addition to the effect part casing the effect part comprises a tubular unit arranged coaxially in the effect part casing. The effect part casing and the tubular unit are connected with spoke elements which extend in the longitudinal direction of the effect part and along parts, particularly substantial parts, of same. The new shell can be made at a very low cost, has a small risk zone at impact, and gives a good indication effect and great safety in the barrel.
