The Sellier & Bellot .300 Winchester Magnum 180 gr SPCE ammunition (manufacturer part number V340852) is engineered for medium to big-game hunting and precision zeroing. Featuring a Semi-Jacketed Soft Point Cutting Edge (SPCE) bullet #2935, this cartridge incorporates an exposed lead nose supported by a stepped mechanical shoulder. This shoulder locks the CuZn 10 alloy jacket to the lead core to control expansion, while cutting a clean, circular entry hole in game hides to produce distinct blood trails. Developed for sporting bolt-action and semi-automatic rifles chambered in standard .300 Win Mag, each cartridge delivers a muzzle velocity of 895 m/s and 4,686 J of muzzle energy from a 600 mm test barrel.

Key Features

• SPCE Cutting Edge Profile: The stepped jacket shoulder mechanically limits core separation during terminal penetration and punches a clean entry hole to facilitate tracking.
• Terminal Energy Delivery: Produces 4,686 J of energy at the muzzle, retaining 3,799 J at 100 m, 3,046 J at 200 m, and 2,416 J at 300 m.
• Trajectory Envelope: Ballistically tuned for a Most Recommended Distance (MRD) zero of 180 m, tracking +3.7 cm high at 100 m, -2.7 cm at 200 m, and -28.0 cm at 300 m.
• Reloadable Factory Brass: Constructed with non-corrosive Boxer primers and standard factory brass casings.

Who is the S&B Sellier & Bellot 300 Win Mag 180 Grain Spce Cutting Edge Ammo 20 Rd for?

• Medium to big game hunters — Delivers 4,686 J of muzzle energy and controlled expansion through an exposed lead core backed by a jacket-locking shoulder, providing reliable penetration on deer, feral boar, and goats out to standard hunting ranges.
• Sport shooters zeroing and practicing at standard ranges — Achieves consistent internal ballistics with an 895 m/s muzzle velocity and a predictable trajectory tuned for an optimal 180-metre zero, keeping vertical drop to -28.0 cm at 300 metres in rifles chambered for .300 Win Mag hunting ammunition.

Less suitable for: Extreme long-range hunting beyond 400 metres, where the stepped profile and 0.353 G1 ballistic coefficient shed velocity rapidly; higher-BC, polymer-tipped boat-tail ammunition is better suited to maintain flatter trajectories and greater retained energy at extended distances.
