REMINGTON UD - 12 GA - 2.75" - #4 BUCK - 21 PEL - 5 RDS/BOX

#4 buckshot pellets are smaller in diameter than 00 buck, but the trade-off is a significantly higher pellet count — this load puts 21 projectiles downrange versus the typical 8–9 pellets in a 00 buck 2.75" shell. The increased pellet count means a denser pattern and greater likelihood of multiple hits on target at close range, though individual pellets carry slightly less energy than the larger 00 pellets. Many home defenders prefer #4 buck for its balance of stopping power and reduced over-penetration risk compared to larger buckshot sizes.

Remington UD loads are designed to function in standard 12-gauge pump-action and semi-automatic shotguns chambered for 2.75" shells. As with any ammunition, it's a good idea to test a box through your specific firearm before relying on it for defensive use, since gas-operated semi-autos can occasionally be sensitive to velocity and pressure variations. These loads are built to Remington's consistent quality standards, making feeding and cycling issues uncommon in properly maintained shotguns.

At typical indoor and close-quarters distances — generally under 25 yards — this 21-pellet #4 buck load produces tight, effective patterns well-suited for defensive or hunting applications. Pattern spread increases with distance, so it's recommended to pattern your specific shotgun at your intended engagement distance to understand how the load performs. Choke selection also plays a significant role: a cylinder or improved cylinder choke is commonly recommended for buckshot to preserve pellet count integrity and optimize spread.
