Rainbow Demon --- I believe your P.S. is at least partially correct --- for a less than heavyweight target rifle. {pardon me... since I don't know how to bring your P.S. quote to my post} --- You have a straight line force in in the direction opposite to the travel of the projectile and powder gas. It contributes the major component of recoil.
You have a rotational force or torque opposite the direction spin is imparted to the bullet. It contributes the minor part of recoil, a rotational recoil. Both effects are recoil, and combined are the total recoil. A heavyweight target rifle, could possibly overcome the effect of minor rotational recoil.
