You learn something new every day. I wonder if the energy of 1 pellet is enough or it's more of a collective effort ? Does anyone know what the average energy of 1 BB pellet @50yrds would possibly be? Couldn't be going faster than a .22lr surely?. Cheers.
There is a point where a shotgun charge transforms from a slug into separate pellets. At close-range you basically blow a huge hole through your target with the massive energy - 1500fp-lbs or more.
Velocity will depend on your ammo, a lot of it will be going faster than most .22LR ammo.
But the energy of each pellet is very low, and spheres dump velocity very quickly, more so if they're deformed from firing. Just the difference between using US BB's and our BB's could be as much as 5ft-lb (20ft-lb to 16ft-lb) for each pellet at 50m range. As the shot charge is also quite long - perhaps a meter or two, not many of the pellets are dumping their energy into the target simultaneously.
