The Sellier & Bellot 16 Gauge 2⅝” (16×67.5) Special Slug 27g is a specialised shotgun cartridge engineered for close-to-medium-range hunting and competitive shooting disciplines. Designed for firearms chambered in 16 gauge with a minimum chamber length of 67.5 mm, this cartridge fires a 27 g (approximately 417-grain) solid lead projectile at a muzzle velocity (V2) of 420 m/s (1,378 fps). The projectile integrates a rear polymer stabilizer wad that prevents in-flight tumbling through smoothbore barrels, eliminating the necessity for rifled chokes or dedicated slug barrels.

Key Features

• Integrated Polymer Stabilizer: Utilises an attached polymer base wad that maintains aerodynamic stability and prevents yawing in smoothbore barrels without relying on rifling.
• Intermediate Hull Length: Built with a 67.5 mm (2⅝-inch) fired hull length to cycle safely through both modern 70 mm chambers and vintage European 67.5 mm shotgun chambers.
• High-Energy Ballistics: Accelerates a 27 g lead slug to 420 m/s at 2 metres from the muzzle, generating high terminal impact ideal for thick-cover hunting.
• Standard Boxer Priming: Features a 10.0 mm brass head height and a reliable W 209 Boxer primer for consistent ignition across ambient Australian field conditions.
• Compact Packaging: Packaged in convenient 5-round commercial boxes suited for range testing or pack transport.

Who is the Sellier & Bellot 16 Gauge 2⅝” Special Slug 27g for?

• Feral pig and deer hunters operating in thick scrub: Needs decisive close-range stopping power, which this 16 gauge shotgun slug delivers via its heavy 27 g lead projectile exiting the muzzle at 420 m/s to drop game within 50 to 75 metres.
• Running boar and slug competition shooters: Requires aerodynamic consistency from smoothbore barrels, provided by this 16 gauge cartridge's attached polymer stabilizer paired with a uniform 67.5 mm hull profile for repeatable cycling.

Less suitable for: Shots past 75 to 100 metres where ballistic drop increases significantly, which are better served by a dedicated centrefire rifle, as well as shotguns with older 65 mm chambers that can suffer chamber-mouth pressure spikes unless verified safe by a gunsmith.
