In addition to the recoil energy (in ft-lbs), the recoil velocity of the gun (in fps) is extremely important in how recoil "feels." Maj.
where [a.sub.x] is equivalent area of recoil brake ventage and [dx.sub.1]/dt is canon recoil velocity.
Plugging in bullet weight, powder charge weight, muzzle velocity and firearm weight one can determine recoil velocity and recoil energy.
Recoil velocity with the 3 1/2 was 22.03 ft/sec as opposed to 18.76 for the 3-inch.
Change the recoil characteristics by varying the weight of the bullet or the weight of the powder charge, thereby changing the time the bullet travels down the barrel and the recoil velocity, and accuracy changes.
Assuming an 8.5-pound rifle for both, recoil velocity is 11.3 fps vs.
According to Kelley, a one-percent asymmetry in the supernova explosion would result in a recoil velocity of about 1,000 kilometers per second.
of recoil energy and 19.0 fps of recoil velocity. In short, our gun is moving at 19 fps to the rear and delivering 33.6 ft.-lbs.
This effect makes it very difficult to cool atoms to a temperature below that corresponding to the recoil velocity of a single photon.
Checking recoil with the KPY ballistics program, the 6-pound 8.6-ounce Cordoba's recoil velocity was 15.71 fps, and the recoil energy (what it feels like on your shoulder) was 26.08 ft/ lbs.
I ran the numbers on a recoil calculator and found they were indeed very similar; depending on the load both have around 16 or 17 fps recoil velocity and 36 to 38 ft.-lb.
The speedier the bullet and the lighter the rifle, the higher the recoil velocity. So a light .300 magnum may not have nearly the recoil energy of a .416, but it can hit you with a vicious snap that is just as unpleasant.
