The Sellier & Bellot Practical Slug 12/63.5 is a specialised 12-gauge shotgun cartridge engineered for dynamic shooting sports. Featuring a compact 63.5 mm (2½”) hull length and a 32-gram (1⅛ oz) lead "Special Slug", this ammunition is tailored to maximise tubular magazine capacity while maintaining cycling reliability. With a factory muzzle velocity of 395 m/s (~1,296 fps), it generates sufficient recoil impulse to reliably operate semi-automatic gas and inertia shotgun systems without introducing excessive recoil during rapid target transitions.

Key Features

• Optimised 63.5 mm Shell Length: Shorter than standard 70 mm (2¾”) rounds, reducing overall stacked length inside tubular magazines to potentially allow an extra cartridge in competition shotguns.
• 32g Lead Special Slug: Incorporates an integral wad and stabiliser tail with a rigid roll crimp closure that resists deformation under magazine spring tension.
• Transparent Casing: Clear plastic hull allows immediate visual confirmation of the slug projectile on the firing line.
• Reliable Semi-Auto Cycling: Delivers a muzzle velocity of 395 m/s for positive ejection and feeding across dynamic practical shooting platforms.
• Packaging: Supplied in boxes of 25 rounds (case quantity: 250 rounds / 11.0 kg).

Who is the Sellier & Bellot Practical Slug 12 Gauge 2½” for?

• IPSC practical shotgun competitors — benefits from the shortened 63.5 mm hull length, which reduces stacked magazine column length to maximise tube capacity while delivering a 32-gram payload at 395 m/s to reliably knock down steel targets and cycle semi-automatic match shotguns.
• 3-Gun shooting competitors — requires the fast handling and managed recoil of this 32-gram 12-gauge shotgun slug, packaged in convenient 25-round boxes to support rapid stage reloading and consistent feeding from extended tubular magazines.

Less suitable for: Target engagements beyond 75 to 100 metres, where aerodynamic drift and ballistic drop make dedicated rifled-barrel sabot slugs or centrefire rifles better suited.
