What produces recoil? Velocity or payload?

[JPH]

Wondering what produces the recoil from a given shell, velocity or weight of payload? Or a combo of both?

 

[Bob Peters]

Both.

I'm not a ballistics engineeer but I will say that shotgun is probably the lightest 12 gauge on the market and less weight tends to add recoil. Its a nice shotgun to carry around but you might not find a good shell that does what you want it to in terms of recoil solely because of the shotgun.

Felt recoil is (Sw x Mv + 4,700 x Pw)2 / (64.348 x Gw)

(The 2 after the first part of the equation is exponent 2... x2)

Sw- shot weight
Mv- muzzle velocity
Pw- powder weight
Gw- gun weight
All numbers in pounds and fps.

Imput a few different scenarios changing shot weight and velocity and make up your own mind

Shoot 1 1/4 ounce lead or bismuth at around 1330fps and you'll be good.

Type of powder has an effect as well

Weight of gun
fit of gun

KEO, how can I get powder weights if it says max dram, or 3 3/4 drams. How do you convert that to pounds?
Thanks

Just use 30grains, which would be 0.00428 pounds. It doesn't matter much in the equation.

Will do. Thank you.
