So... If I have a .30 caliber rifle shooting a 220gr bullet @ 3300fps, how much energy would the bullet have in foot-pounds at the muzzle, and how many foot-pounds of recoil would have to be absorbed by the shooter?
EDIT: Oh, out of a 26", 1-in-11.4" twist moly-coated tube... in case you needed that. Bullet's moly-coated with a ballistic coefficient of .629 and sectional density of .331... I've also got them w/ .631 and .323.
