| 摘要 |
<p>The invention relates to a propellant charge casing consisting of steel, in the case of which the wall thickness (d) of the shoulder cone (4) is reduced by an amount in the range of tenths of a millimetre with respect to the wall thickness (d'') of the casing body (1) in the region adjacent to the shoulder cone (4). This prevents the ammunition jamming in the breech during firing. <IMAGE></p> |
