Do the weapons have the same mass, the same geometry, the same operating principle? "Felt" recoil is much more complicated than case design. There is just no theory of physics (that I know) that can explain how the shape of the case can affect recoil. I get a lot more recoil from my 357 revolver...

Recoil is an inevitable consequence of a powerful firearm. For young guys, its an annoyance. For those of us beyond the Biblical "three score and ten" who take bruise friendly blood thinners, its a bit more concerning - especially if we like to shoot, shoot, shoot.

Case dimensions alone should not affect recoil. Pressure acts in all directions in the chamber, but pressure (and the force it creates on a surface area) are not factors in recoil momentum.

CORRECT! Translational Momentum (recoil in a straight line) is just mV. This means that the momentum of a weapon's reaction will exactly equal the momentum of the bullet and powder gasses ejected from the barrel in a straight line. However, the vector that you feel at the shoulder is Force...
