The Sellier & Bellot SB Corona 12/70 is a field hunting shotshell engineered for clean cycling and consistent patterning across break-action, pump-action, and semi-automatic shotguns. Loaded with a 32-gram (approx. 1⅛ oz) payload of 3.50 mm lead pellets (European No. 3 / UK #2 / US #3), this ammunition produces a muzzle velocity of 385 m/s (1,263 fps). Each shell features a 12.5 mm brass head, a durable plastic hull with a 6-point star crimp, and a plastic shot cup wad designed to protect pellet geometry and sustain downrange kinetic energy.

Key Features

• Optimised Lead Payload: Carries 32 grams of 3.50 mm lead pellets to deliver high impact energy and penetration on larger feathered game and ground vermin.
• Standard Field Velocity: Achieves a muzzle velocity of 385 m/s, balancing shot string density with manageable recoil.
• Reliable Hull Construction: Features a 70 mm plastic hull, 12.5 mm brass head, and 6-star crimp closure for smooth feeding and positive extraction.
• Protective Shot Wad: Incorporates a plastic cup wad that reduces barrel leading and controls pellet dispersion out to moderate field distances.

Who is the S&B Sellier & Bellot 12 Gauge 2¾" 12x70 Sb Corona 3.5mm 32g Uk#2, Us#3 Ammo 25 Rd for?

• Upland game bird hunters — Requiring deep tissue penetration for pheasant and guinea fowl, this 12 gauge hunting shotshell delivers a 32-gram payload of 3.50 mm shot driven at a muzzle velocity of 385 m/s to maintain fatal striking energy within 25 to 45 metres.
• Pest controllers — Targeting medium ground vermin such as foxes, hares, and feral rabbits at intermediate ranges, this 12 gauge hunting shotshell provides a dense pattern of heavy 3.50 mm pellets to ensure clean, humane stops without stepping up to heavy magnum recoil.

Less suitable for: Long-range shooting beyond 45 to 50 metres where pattern density thins, requiring heavier 36g to 42g magnum shotshells; vintage shotguns with short 65 mm (2½") or 67.5 mm chambers; and hunting in designated Australian wetlands or waterfowl zones where lead ammunition is legally prohibited and non-toxic steel, bismuth, or tungsten shotshells are required.
