Shotgun Energy
How efficient are guns?
How efficient are different types of guns such as handguns, shotguns, sniper rifles and assault rifles? Also, what other forms of energy is the energy converted to?
It depends on how you are defining efficiency.
If you are talking about the conversion of chemical energy to kinetic energy (accelerating the bullet), then the rule of thumb is the longer the barrel, the more efficient.
The energy starts as mostly chemical (primer and gunpowder) with just a little bit of kinetic input (impact energy from the firing pin). Then a chemical reaction takes place as the gunpowder explodes and the combustion gases expand. This is converted to heat and kinetic energy (movement of the projectile) as long as the projectile is in the barrel.
If you define efficiency as kills per shot, that depends on the weapon and the user. An Army sniper with a good rifle will be much more efficient than a gang-banger holding a MAC-10 submachine gun sideways over his head as he sprays a rival gang's crack house from the back seat of the pimped-out low-rider zipping by the target with the hydraulics moving the back end of the car up and down!
