The Sellier & Bellot .308 Winchester 180 gr XRG (eXergy) is a factory-loaded, lead-free hunting round engineered for deep penetration and clean game harvesting. Built around an aluminium-tipped monolithic tombac (CuZn 10 alloy) solid bullet, this cartridge replaces traditional lead cores with a concave hollow cavity supported by five internal longitudinal grooves. Upon impact, the bullet deploys controlled flower-petal mushrooming with nearly 100% weight retention and zero core fragmentation. Designed for factory .308 Winchester (7.62×51mm) chambers, each round utilizes a reloadable standard brass case, a non-corrosive Boxer primer, and three exterior guide rings along the projectile shank to minimize bore friction and fouling.

Key Features

• Monolithic Tombac Construction: Fabricated from a solid CuZn 10 copper-zinc alloy with an integrated aluminium tip, eliminating lead core fragmentation and meat contamination.
• Controlled Terminal Expansion: Five internal longitudinal grooves facilitate consistent flower-petal expansion while retaining virtually 100% of projectile mass for deep penetration.
• Friction-Reducing Guide Rings: Three external drive bands engraved into the bullet shank decrease barrel contact, reducing bore fouling and pressure spikes.
• High Energy Output: Generates 3,697 Joules of energy at the muzzle from a standard 600 mm test barrel.
• Standard Reloadable Components: Assembled with factory reloadable brass casings and standard non-corrosive Boxer primers.

Who is the S&B Sellier & Bellot 308 Win 180 Grain Xrg (Exergy) Lead Free Ammo 20 Rd for?

• Hunters targeting deer, wild boar, or feral pigs in lead-restricted zones — Requires 100% non-lead monolithic construction that delivers 3,697 Joules of muzzle energy to legally and ethically dispatch heavy game without core fragmentation.
• Meat harvesters requiring high weight retention — Utilises a heavy 180 grains solid tombac bullet with a G1 ballistic coefficient of 0.287 that initiates controlled mushrooming at a 795 m/s muzzle velocity, ensuring deep tissue penetration without leaving toxic lead shards in edible meat.

Less suitable for: Rifles with slow-twist barrels of 1:12" or slower that cannot properly stabilize long monolithic 180-grain projectiles, which are better served by lighter 130–150 grain lead-free bullets; and engagements past 300 metres where velocity drops below 513 m/s, which are better served by traditional bonded soft point ammunition with lower expansion thresholds.
