with (6), as already explained »indicated · Hüleen-like» Discarded echo guiding rings which were produced according to the invention have many advantages the following:

a) Disintegration into small pieces of the DF after firing;

b) very good moisture resistance properties;

c) the ability to have high cannon temperatures. to resist en;

d) good aerodynamic shape for the projectile and consequently better accuracy because the Hing

- moves away from the projectile immediately after the projectile leaves the bullet;

e) simple monitoring processes j

f) after the mooring to the floor there are no more Editing operations required;

g) simple and easy replacement in case of damage in the field;

h) Satisfactory function of the projectile at low levels Chamber printing. -
