[QUOTE="jrsolocam, post: 979905, member: 24511"] What is the least amount of energy required to make x amount of energy at x distance. That would be efficiency. A loaded cartridge has potential energy and a bullet in flight has kinetic energy. PE is determined by the charge weight, specific heat of the powder, and bullet mass. When fired the pe loses most of the energy through heat and recoil, with the balance sending the bullet off. That's when BC comes into play. Norma's new manual talks about it a little bit. Someone here smarter than me could derive a formula that would solve this... [/QUOTE]
