In addition to the recoil energy (in ft-lbs), the recoil velocity
of the gun (in fps) is extremely important in how recoil "feels.
Plugging in bullet weight, powder charge weight, muzzle velocity and firearm weight one can determine recoil velocity
and recoil energy.
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.
The accompanying chart shows recoil velocity
(RV) and recoil energy (RE) for a range of cartridges.
According to Kelley, a one-percent asymmetry in the supernova explosion would result in a recoil velocity
of about 1,000 kilometers per second.
This effect makes it very difficult to cool atoms to a temperature below that corresponding to the recoil velocity
of a single photon.
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.
The accompanying chart provides examples of both gun weight and bullet weight, and you can see how both recoil velocity
and recoil energy are affected.
Gun weight makes a big difference in recoil energy (how hard it hits you), bullet velocity makes a difference in recoil velocity
(how fast it hits you) and stock fit plays a big role in felt recoil (the way it hits you).
To compute recoil energy, square recoil velocity
, multiply the result by gun weight in pounds, and divide the product by 64.
While gun recoil energy is high, gun recoil velocity
The primary issue facing the gun companies is the recoil velocity
from the little .
