Shooting paper with 12 gauge 3.5 turkey shells and 3" slugs are the worst I have ever been kicked. I am pretty sure the worst ever was the day I shot 12-15 Nitro 3.5" shells through my Rem 870 trying to get the POA to coincide with the POI. I finally managed after an hour and a half shooting and a slightly bruised/blackened cheek bone. I'd be willing to bet the Nitro 3.5" shells with 2 7/16 shot is worse than the 78 ft/lbs listed here. They kill on both ends when you are shooting paper. I never seem to notice the kick when shooting an ol' bird.
