摘要：The aim of the invention is to ensure the firing stability of a full-caliber trainingprojectile (1) in an inexpensive manner, said training projectile comprising a solid headpart (2) and a tubular fin body (3) which adjoins the rear side of the head part (2).According to the invention, this is achieved by designing the fin body (3) such that thepropellant gases produced upon firing the training projectile (1) also act on the exterior(5) of the lateral wall (6) of the tubular fin body (3). For this purpose, a guiding system (7)is provided in the rear region of the fin body (3), said guiding system comprising a guidingstrip (9) which is received by an annular groove (8) of the fin body (3). The guiding strip (9)has multiple web-shaped guiding elements (10) which are uniformly distributed over thecircumference of the fin body (3) and which support the fin body (3) against the inner wallof the corresponding barrel. Furthermore, a sealing system (12) is arranged in the regionof the solid head part (2) of the training projectile (1) in order to prevent the propellantgases from passing by the exterior of the training projectile (1) within the barrel.
