Russian 'Pion' destroys Ukrainian military targets

I like it how the modern guns are so full on with their alloys, machining and heat treatment etc., can produce barrels with breech pressures high enough to sound like giant high powered hunting rifles - as if the powders are not reaching the transition point from rapid combustion to explosion - but they are using very fast burning mixtures of nitrated propellant, that give the brown / yellow smoke and burn at a rate say 10% below detonation pressure and temperature.

I think cordite is a mixture of cellulose, nitric acid (gun cotton) and the resultant is then mixed with vaseline to drop the temperature and slow the burning rate down - AND these powders are mixtures of gun cotton AND cordite.....
