The 1.75-inch 12-gauge loads are offered with three different payloads: No. 8 birdshot, No. 4 Buck, and a rifled slug. Of those choices, the No. 4 Buck is most useful for home defense. The 15 pellets are formidable medicine for any would-be attacker, but the smaller size keeps muzzle blast down, which can be disorienting in the tight confines of a hallway. Federal states the muzzle velocity is 1,200 feet per second, so there’s as much knockdown power as the shell’s full size brethren.
