I am not sure on the details, but I am sure that B.L.E. was correct as far as the 'it is because you double the weight of the projectile without doubling the weight of the gun.' I believe the actual recoil is only 2x, but the felt recoil is much more. I think you are applying the same acceleration from twice the mass to the same mass so you get double the acceleration.
F=MA
Mass of bullet X Accelleration of Bullet = Mass of Gun X acceleration of Gun
2Mass of Bullet X Acceleration of Bullet = Mass of Gun X 2 acceleration of Gun

But I did get C in Physics.
