About 30 % of the chemical energy from gunpowder is transfered to kinetic energy of the bullet. So the percantage of the pressure energy transfered to the kinetic energy of the bullet is even higher. A top quality pcp transfers roughly 21-22 % of the pressure energy to kinnetic energy of the...

Nitrogen is faster than oxygen. And air contains both nitrogen and oxygen. When I weigthed the expansion rate of oxygen and nitrogen in proportion to their share of the air content I got a combined expansionrate that was lower than for nitrogen alone. I got the result that nitrogen would give...
