Nepolit was an explosive used in experimental shelless grenades. I don't know
if it was ever fielded. While I have no proof one way or the other I seriously
doubt it was tried in caseless small arms ammunition. In any event the
technology flopped.

Stick to a/c Dan. Nipolit was invented by WASAG and experimented with
in a wide range of applications such as: shaped explosives, caseless
grenades, disc grenades (85mm diameter, 13mm thick with egg type
detonator inserted in core), anti-tank charges, and caseless
ammunition in the end. Original Nipolit grandes were used in combat
and examples are still found in museums today.
Dynamit-Nobel picked up where WASAG left off...

If you want military book references there are plenty around.
