For home defenders and tactical shotgunners, Remington Express Magnum 12 gauge buckshot ammo delivers twelve pellets of #00 buckshot at 1290 feet per second from a 2-3/4-inch shell. Each round launches .33-caliber lead spheres backed by a granulated polymer buffer that cushions the shot column during acceleration, preserving pellet roundness and producing tighter patterns than unbuffered loads. The 2-3/4 dram equivalent powder charge maintains velocity consistency across smoothbore and cylinder-choke barrels, balancing recoil control with terminal performance inside 25 yards. Brass-plated hulls wear evenly through extraction cycles; non-corrosive Boxer primers support reloading when components are available.
Built for the Box
Remington loads these rounds with twelve .33-caliber lead pellets — a standard #00 buckshot count — over a cushioning wad system that includes granulated polymer buffer media. During firing, the buffer fills voids between pellets, preventing deformation as the shot column accelerates down the bore. The result: rounder pellets that resist flattening, fly straighter, and group tighter on target. Muzzle velocity of 1290 feet per second places this load in the “magnum” category for 2-3/4-inch shells, delivering approximately 2450 foot-pounds of muzzle energy across the twelve-pellet payload. The six-point star crimp secures the payload, resists jostling during transport, and opens cleanly during firing. Brass-plated steel hulls shed moisture and resist corrosion; reloadable construction extends hull life when paired with appropriate wads and primers.

This load patterns predictably through improved-cylinder and modified chokes, though full chokes may constrict too tightly for buffered buckshot loads. Five-round boxes keep costs manageable for pattern testing and zero confirmation. Review current 12 Gauge Buckshot Ammo options for alternative pellet counts and velocity profiles.
Safe Handling & Compliance
Federal law requires purchasers to be at least 18 years old for rifle and shotgun ammunition, and at least 21 for handgun ammunition. Ammunition cannot be shipped to certain states, counties, and cities — review our ammunition shipping restrictions before ordering. Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users.
- Four rules: Treat every firearm as loaded, finger off trigger until on target, identify target and what lies beyond, never point at anything you do not intend to shoot.
- State and local laws: Verify buckshot possession and use restrictions in your jurisdiction — some localities prohibit buckshot for hunting or impose magazine capacity limits.
- Lead exposure: This product contains lead, known to the State of California to cause cancer and reproductive harm. Use proper ventilation during firing, wash hands after handling ammunition, and review Proposition 65 guidance.
