Hornady Critical Defense 8-pellet 2 3/4 12 gauge buck 1600 fps
Federal Premium Law Enforcement 8-pellet 2 3/4 12 gauge buck 1145 fps aka Federal 13300LE LOW RECOIL
With the Hornady CD ammo at 1,600 FPS and the low recoil Federal 13300LE at 1,145 fps this isn't an apples to apples comparison. Naturally there's much more felt recoil with the Hornady 00 buck over low recoil ammo. Personally I prefer the Federal 12700LE (1,325 fps with nine 00 pellets) Flite Control because of not just better accuracy downrange but also better energy retention on target.
