The Sellier & Bellot 6.5 × 55 SE TXRG (eXergy Blue) 120 GRS is lead-free centerfire rifle ammunition engineered for medium-game hunting. Loaded with a 120-grain (7.80 g) monolithic solid copper bullet, this cartridge features a blue polymer tip and an engineered expansion cavity designed to initiate rapid, controlled hydraulic expansion while maintaining near-total weight retention. Built with CuZn 30 brass cases and an overall cartridge length of 76.00 mm, it produces a factory-tested muzzle velocity of 863 m/s (2,831 fps) and a muzzle energy of 2,905 J from a standard 600 mm test barrel. The projectile incorporates relief grooves along the shank to manage in-barrel friction and a boat-tail profile delivering a G1 ballistic coefficient of 0.414.

Key Features

• Monolithic Copper Construction: Formed from solid copper to eliminate lead fragmentation in meat, providing non-toxic terminal performance and near-100% weight retention.
• Polymer Tip and Expansion Cavity: The blue polymer tip enhances aerodynamic efficiency and drives uniform mushrooming across varied impact velocities.
• Low-Drag Profile: Features an aerodynamic boat-tail base and shank cannelure grooves to reduce bore resistance and maintain a flat trajectory, yielding an optimal neutral sight-in range of 176 metres.
• Substantial Downrange Energy: Retains 2,010 J of energy at 200 metres and 1,347 J at 400 metres for effective terminal delivery at extended hunting distances.

Who is the S&B Sellier & Bellot 6.5x55 Se 120 Grain Txrg Blue Lead Free Ammo 20 Pack for?

• Medium-game deer hunters — Requires non-toxic meat harvesting when targeting fallow, red, or chital deer, utilizing this 6.5x55 SE lead-free hunting ammunition to deliver 2,905 J of muzzle energy at 863 m/s alongside high weight retention.
• Feral goat and pig hunters — Uses Swedish Mauser rifles across open country, where the 120-grain projectile and a G1 ballistic coefficient of 0.414 provide the flat trajectory and terminal penetration needed for medium pest species out to a 176-metre optimal neutral sight-in range.

Less suitable for: Hunters targeting large, heavy-boned game such as mature sambar stags or scrub bulls, who require deeper penetration from heavier 140- to 160-grain bonded projectiles or larger calibres; strictly incompatible with rifles chambered for 6.5 Creedmoor or 6.5 PRC.
