The same supressor??
There is no comparison between shotgun and rifle recoil, apples and oranges!
The difference is not only the amount of force but the amount of time it is released.
The 'sharp' recoil of a rifle is the result of the large amount/mass of propellant used (compared to a shotgun) and velocity of the released 'mass', thus a faster/sharper 'punch' and the recoil of the rifle, the recoil of the projectile is secondary. Where as the shotguns primary recoil is from a larger projectile mass and the smaller charge of the propellant leaving the muzzle at a lower velocity is secondary. I call this the 'rocket effect' (from the hot gasses). Thus a GOOD/efficient muzzle brake will redirect this high velocity (5500 to 6000 fps) gas at right angles and nullify the 'rocket effect' making the rifle more of a 'push', like a shotgun, and less like the normal rifle 'punch'!
