Hello Tony,
To my knowledge
Nitropenta is not a mixture of Penthrite and wax. It's a commercial name for pure Penthrite, very often used in Europe. Montan wax is a type of wax produced from lignite (brown coal).
I've also noticed that according the german documents which describe the MG151/20 rounds, the explosive component in the round is always Nitropenta + a certain percentage of phlegmatizer. The phlegmatizer is wax.
Furhter, incendiary rounds (Brandgeschosse) are mosty a combination of Nitropenta, wax and Elektron-Thermite or Phosphorus. Only Minen-Geschosse used the HA.41 composition.
all the best,
Tomislav
