30mm Practice Round
- Thread starter RogerKP
- Start date
Probably had all the remnant paint wire brushed off, as the rotating band looks freshly cleaned also. Most of these round were dumped in water at the end of the war, and divers dig through the silt on the bottom of the lakes, recover the ammo, and inert it over the winter. The silt kept the oxygen from the metal components, so they can be in very good condition, except for the paint.
Not sure of the chemistry, but it is a tar-like substance.

It is not uncommon to find German canon ammunition without paint - the stencil was applied to the bare metal and then a lacquer applied. It is most common among practice rounds but other projectiles have been found too.
As for the 3cm practice round, some have been found containing tar or bitumen, with or without sand. This projectile is usually referred to as an "Anschiessgranate" or "ranging shell". Whether or not these particular shells with the domed zinc plug were used with an internal instability bar (to reduce range) and as such an "Uebungsgranate" or "practice shell is currently unclear to me.

Joerg,
kommen die dann immer mit den Gewichtsausgleichstab? Warum ist da nichts ueber dieses Geschoss in Der Handbuch der Flugzeug Bordwaffenmunition 1936 - 1945?
Do they always come with the balance - bar? Why is there no mention of this projectile in the above-mentioned book?
