For elk at 600 yards or Cape buffalo in thick brush, the Swift High Grade 338 Lapua Magnum 210gr Scirocco II bonded polymer tip delivers precision long-range ballistics and deep, controlled expansion. This 338 Lapua Magnum ammo pushes a 210-grain bonded soft-point to 3067 fps from a 24-inch test barrel, generating 5222 ft-lbs of muzzle energy — enough authority for any North American game and most African plains species. Swift hand-inspects each round, chambers every case to SAAMI specification, and applies HERNON water-tight sealant to primer and case mouth, ensuring function in sub-zero mountain camps and monsoon-soaked blinds.
Load Profile
The Scirocco II bonded core locks jacket to lead through a proprietary bonding process, preventing core-jacket separation on heavy bone impact. The secant ogive nose profile and 15-degree boat tail base yield a G1 ballistic coefficient of 0.507 and sectional density of 0.263 — both figures translate to retained velocity past 800 yards and predictable wind deflection. Swift sources brass that meets or exceeds SAAMI dimensional tolerances, then sizes each case individually to guarantee chambering across match chambers and factory sporting rifles. Boxer primers allow for straightforward decapping and repriming; non-corrosive propellant keeps bores clean after extended string fire.

Expect over 70% weight retention on heavy quartering shots through shoulder blade and rib, with mushroom diameters approaching twice the original caliber. The polymer tip initiates expansion at impact velocities above 1800 fps, while the bonded core holds together through dense muscle and bone.
