The Sellier & Bellot Steel Shots Magnum 36 (Model: V066152) is a high-performance 12 gauge waterfowl shotgun cartridge engineered for hunting in lead-restricted environments. Loaded with a heavy 36-gram (approximately 1 1/4 oz) payload of non-toxic steel shot, it fires at a muzzle velocity of 390 m/s (1,280 fps). Featuring a 76 mm (3-inch) plastic hull with a 12.5 mm metal head and a six-star crimp, each round incorporates an engineered, full-length plastic wad that completely encases the 4.06 mm steel pellets to shield shotgun bores and chokes from abrasion.

Key Features

• Non-Toxic Steel Payload: Delivers 36 grams of 4.06 mm steel shot (nominally 4.0 mm, equivalent to UK #BB / US #1) for deep penetration on heavy wetland game.
• High-Velocity Ballistics: Achieves an exit velocity of 390 m/s to maximise downrange kinetic energy and pellet impact at ranges between 30 and 45 metres.
• Protective Shot Cup: Uses a heavy-duty, high-density plastic wad that encloses the steel shot column to prevent bore scoring and internal barrel wear.
• Magnum Hull Construction: Built on a 76 mm (3") plastic case with a 12.5 mm brass-plated head and six-star crimp for reliable feeding and cycling in modern magnum shotguns.
• Lead-Free Regulation Compliance: Formulated specifically to meet statutory non-toxic ammunition requirements across protected waterways and wetland reserves.

Who is the S&B Sellier & Bellot 12 Gauge 3" Steel Shot 4.0mm 36g Ammo for?

• Waterfowl hunters targeting geese and larger ducks in wetland reserves — provides this 12 gauge steel waterfowl shotgun shell with a heavy 36-gram payload of 4.06 mm pellets propelled at 390 m/s, delivering the penetration and pattern density required for large-bodied birds at distances of 30 to 45 metres.
• Hunters bound by statutory bans on lead ammunition in waterways — complies fully with non-toxic wetland hunting mandates by utilizing a 100% lead-free steel shot charge encased in a 3-inch (76 mm) hull.

Less suitable for: Shotguns with standard 65 mm (2 1/2") or 70 mm (2 3/4") chambers, firearms not stamped with modern "STEEL SHOT" or "BILLES D'ACIER" proof marks, or chokes tighter than Modified (1/2 choke); these configurations require shorter standard-pressure 70 mm lead or steel field loads paired with open choke constrictions.
