For home defense shooters working with pump-action platforms, the Aguila Minishell 12 Gauge Buckshot solves the capacity problem without requiring magazine extensions or aftermarket parts. These 1-3/4″ shells — nearly an inch shorter than standard 2-3/4″ loads — fit twice as many rounds into the tube of a Mossberg 500, Remington 870, or similar pump gun. You load eleven pellets per shell: a mix of #1 buck (0.30″ diameter, 40 grains each) and #4 buck (0.24″ diameter, 20.7 grains each), launched at 1200 feet per second. Aguila stakes its reputation on delivering reliable ignition and consistent patterning at defensive ranges, and the Minishell line extends that legacy into a form factor engineered for tighter spaces and reduced felt recoil.

The mixed-pellet payload balances penetration and spread: #1 buck carries more energy per pellet for barrier work, while #4 buck increases hit probability at close range. Boxer primers and non-corrosive propellant keep fouling minimal, and the 6-point star crimp ensures reliable feeding in autoloaders that cycle the shorter shells. For shooters stocking a defensive shotgun, the capacity gain and recoil reduction make the Minishell format worth a full pattern session at seven yards.
