The Sellier & Bellot 12 Gauge 3" (12x76 mm) Magnum Buck Shot ammunition (SKU V211612) is engineered for medium-game hunting, predator control, and pest eradication. Loaded with a heavy 53-gram (approximately 1 7/8 oz) payload of 5.1 mm lead shot (UK #AAA), this cartridge generates a muzzle velocity of 370 m/s (1,214 fps). It utilises a traditional felt wad system within a 76 mm magnum casing, providing consistent pressure sealing and dense shot patterning at close to moderate ranges. Packaging contains 10 rounds per box.

Key Features

• 53g Magnum Payload: Packs 53 grams of 5.1 mm lead pellets to deliver high pellet counts and maximum kinetic energy transfer on target.
• Ballistic Velocity: Produces a consistent muzzle velocity of 370 m/s from its 12x76 mm configuration.
• Traditional Felt Wad: Uses a felt wad design to establish a positive gas seal in the barrel, facilitating uniform pressure and reliable pattern distribution.
• Magnum Construction: Built with a 12.5 mm brass head height on a 3-inch shell case to withstand magnum internal operating pressures.

Who is the S&B Sellier & Bellot 12 Gauge 3" 12x76 Buck Shot 5.1mm 53g Uk#Aaa Ammo 10 Rd for?

• Feral pig hunters targeting quarry at close quarters — requires the maximum knockdown power of a heavy 53-gram lead payload fired at 370 m/s, making this 12-gauge buckshot ammunition effective for delivering massive energy transfer on tough animals within dense scrub.
• Pest controllers managing wild dogs and feral foxes — benefits from the dense pattern produced by 5.1 mm diameter shot across typical operating distances of 25 to 40 metres, giving this buckshot load an ideal balance of pellet coverage and lethal penetration on medium-sized predators.

Less suitable for: Firearms with 70 mm (2 3/4") or 65 mm (2 1/2") chambers, as well as engagements beyond 40 metres; shotguns with shorter chambers require standard 70 mm shotshell loads to prevent unsafe pressure spikes, while targets beyond 40 metres require solid shotgun slugs or centrefire rifles to maintain humane terminal ballistics.
