recoil vs felt recoil?

I assume you can change felt recoil without reducing real recoil

However, is it possible that real recoil could be reduced but felt recoil is not changed?


How do you actually calculate real recoil on a shotgun?


I assume there is no way to calculate felt recoil because it is subjective.
 
Real recoil.

The momentum of the shotgun = the momentum of the shot, wads, and powder gasses.

Momentum is not kinetic energy. The recoil energy is not the same as the bullet's energy. Energy divides up according to the ratio of gun to bullet weight. The heavier the shotgun, the less the real and felt recoil will be.
My rule of thumb,to be able to shoot 100 rounds in a row at trap or skeet comfortably without flinching, the gun needs to weigh about 100 times as much as the shot charge.

Oversimplifying, that is, ignoring the mass of the gunpowder and wads, if a gun weighs 100 times as much as the shot, the gun will have 1/100 the shot's energy.
If the gun weighs 200 times as much as the shot, the gun will have 1/200th the shot's energy,
and so forth.

Like others said - Felt recoil varies a lot for each person ( and their grip, fundamentals, etc ) and if you have a gun that has some mechanical device designed to absorb the recoil ( GraCoil system, Benelli Comfort Tech system, a gas operated semi-auto, and a lot of other air or hydraulic supression systems out there )...

The only useful comparison / is to calculate the Real Recoil based on the formulas that OneOunce provided.

Run the numbers - and you'll see that a 12ga doesn't always have more recoil than a 20ga ( especially in a very light 20ga gun ) which they often are.
 
A stock that's too short for you will hammer your cheekbone.

I like a Monte Carlo style stock for trap. It allows your head to be more upright so that the recoil doesn't drive your cheek into the stock as much.

Lifting your head off the stock will make you shoot over the bird everytime and if your cheek is bruised, it's almost impossible not to unconsiously lift your head before pulling the trigger.
