Federal Power-Shok #1 Buck (16 Pellet)

Federal Power-Shok #1 buck is the load that ballistics nerds reach for, and the reasoning holds up. A standard 2-3/4 inch shell holds sixteen #1 buck pellets versus nine 00 pellets. Each #1 pellet is .30 caliber, and per the International Wound Ballistics Association, #1 is the smallest buckshot size that reliably and consistently penetrates more than 12 inches of ordnance gelatin at typical engagement distances, the FBI's benchmark for adequate penetration. That means you get nearly double the pellet count, and therefore more potential wound channels, without dropping below the penetration floor that disqualifies smaller birdshot and #4 buck for serious defensive use.

The total cross-sectional area of sixteen #1 pellets exceeds that of nine 00 pellets, so on paper #1 buck produces more potential effective wound trauma per shot. The catch is availability and patterning: dedicated tactical #1 buck loads are rare, and this Power-Shok offering uses a conventional wad rather than FLITECONTROL, so patterns are wider than the purpose-built defensive loads. You give up tight patterning to gain pellet count.

For a home-defense shotgun where engagement distances are short and over-penetration is a concern, #1 buck is a legitimate, arguably optimal choice. Pattern it carefully, because the wider spread means you need to confirm your gun keeps all sixteen pellets where you want them at your expected distances.
