The rearward energy of the firearm is the free recoil and the forward energy of the bullet is the muzzle energy. The concept of free recoil comes from the tolerability of gross recoil energy. Trying to figure the net recoil energy of a firearm (also known as felt recoil) is a futile endeavor. Even if the recoil energy loss can be calculated ...
The .243 Winchester has also been found to shoot flatter and more accurately than the 7mm-08 Remington out to 500 yards, with less recoil yet also less terminal energy. [11] (Left to right) .223 Rem, .243 Win, .308 Win. The recoil has been measured to be so light that it "can be shot by anyone that can handle a rifle."
Pellet exiting muzzle, with formula for energy overlaid.. Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indication of the destructive potential of a given firearm or cartridge.
Illustration of forces in muzzle rise. Projectile and propellant gases act on barrel along barrel centerline A. Forces are resisted by shooter contact with gun at grips and stock B. Height difference between barrel centerline and average point of contact is height C. Forces A and B operating over moment arm / height C create torque or moment D, which rotates the firearm's muzzle up as ...
Loads for waterfowl will tend to produce more felt recoil in a 12-gauge shotgun than in a 20, but this may not be the case depending on the gun used. [9] Full-power 20-gauge shells fired from a light 5 lb (2.3 kg) gun will have more felt recoil than those fired from a heavy 7 lb (3.2 kg) gun. [11]
For example, gas-operated shotguns are widely held to have a "softer" recoil than fixed breech or recoil-operated guns (although many semi-automatic recoil and gas-operated guns incorporate recoil buffer systems into the stock that effectively spread out peak felt recoil forces.) In a gas-operated gun, the bolt is accelerated rearwards by ...
The .243 Winchester Super Short Magnum or .243 WSSM is a rifle cartridge introduced in 2003. It uses a .300 WSM ( Winchester Short Magnum ) case shortened and necked down to accept a .243in/6mm diameter bullet, and is a high velocity round based on ballistics design philosophies that are intended to produce a high level of efficiency.

WSM and WSSM family of cartridges. From left to right: .223 WSSM, .243 WSSM, .25 WSSM, .270 WSM, 7 mm WSM, .300 WSM, .325 WSM. Winchester Super Short Magnum, or WSSM is a line of rebated bottlenecked centerfire short magnum cartridges introduced by the U.S. Repeating Arms Company (Winchester Inc). [1]
