The Sellier & Bellot .308 Winchester 165 Grain eXergy EDGE (TXRG Edge) is lead-free centrefire rifle ammunition engineered for medium-to-large game hunting. Constructed from a solid, monolithic tombac alloy, this cartridge incorporates an integrated cutting-edge shoulder and a red polymer tip. When fired from a standard 600 mm test barrel, it produces a muzzle velocity of 829 m/s and 3,677 Joules of muzzle energy. The polymer tip initiates rapid terminal expansion upon impact, while the monolithic body retains nearly 100% of its weight to deliver deep straight-line penetration without lead fragmentation.

Key Features

• Monolithic Tombac Construction: Made from a solid non-lead copper alloy that eliminates bullet breakup and prevents core-jacket separation.
• Cutting Edge Profile: Features a sharp shoulder design that cuts clean, circular entry holes in game tissue to facilitate immediate and visible blood trails.
• Polymer Tip: Streamlines the projectile for external ballistics while driving controlled, uniform expansion across typical hunting velocities.
• Clean Meat Recovery: Retains its mass through dense bone and muscle tissue, avoiding the dispersion of toxic lead particles in harvested game meat.
• Factory Ballistics: Features a G1 ballistic coefficient of 0.357 and a manufacturer-recommended zero (MRD) set at 167 metres.

Who is the S&B Sellier & Bellot 308 Winchester 165 Grain Txrg (Exergy) Cutting Edge Lead Free Ammo 20 Pack for?

• Hunters targeting feral pigs and deer in non-lead mandatory zones — Complies with non-lead environmental mandates by utilising a 165 grains monolithic tombac projectile that drives an initial muzzle velocity of 829 m/s for clean, humane harvesting of species such as wild boar, fallow deer, and sambar.
• Hunters prioritising clean meat harvesting with minimum lead fragmentation — Retains nearly 100% of its 165 grains bullet mass upon terminal impact, using a solid non-lead alloy with a G1 ballistic coefficient of 0.357 to prevent fragment dispersion and avoid meat contamination.

Less suitable for: Long-range hunting beyond 350 metres where downrange velocity drops near the 550–600 m/s threshold required for reliable monolithic expansion; high-BC soft-point or match-grade cup-and-core hunting bullets are better suited for extended long-range applications.
