The Norma ECOSTRIKE .375 Holland & Holland Magnum 250gr (product number 20195502) is a lead-free, non-toxic expanding hunting cartridge engineered for medium to heavy big game. Loaded with a 250-grain (16.2 g) monolithic copper projectile featuring a nickel coating and polymer tip, it delivers flat trajectories, high weight retention, and deep penetration across varied engagement distances. Tested from a 660 mm (26 in) barrel, it produces a muzzle velocity of 820 m/s and 5,446 J of muzzle energy, retaining 3,154 J at 300 metres with a Most Recommended Distance (MRD) zero of 166 metres.

Key Features

• Lead-Free Monolithic Copper Core: Solid copper construction delivers near 100% weight retention and deep penetration without lead contamination in game meat.
• Nickel-Coated Exterior: Reduces barrel fouling and friction during passage through rifled barrels.
• Aerodynamic Polymer Tip & Boat-Tail: Produces a 0.438 G1 ballistic coefficient (0.219 G7) while preventing tip deformation in the magazine under heavy recoil.
• Flatter Big-Bore Trajectory: At 250 grains and 820 m/s, it shoots faster and flatter than traditional 300-grain .375 H&H loads out to 300 metres.

Who is the Norma ECOSTRIKE .375 H&H 250gr for?

• Sambar deer hunters in heavy timber or mountain ranges — requires the 5,446 J of muzzle energy and near 100% weight retention delivered by this .375 H&H hunting ammunition to drive through heavy bone and dense cover.
• Feral camel and scrub bull hunters in the Australian outback — benefits from the 820 m/s muzzle velocity and 0.438 G1 BC of this .375 H&H cartridge, which provides a flatter trajectory and retains over 3,150 J of energy at 300 metres for open-country shots.
• Water buffalo hunters requiring non-toxic projectile compliance — utilizes the 250-grain solid copper expanding design to achieve deep penetration on heavy-framed game without lead fragmentation.

Less suitable for: Thick-skinned dangerous game where stopping charges require strictly non-expanding penetration; for those applications, traditional 300-grain bonded bullets or solid non-expanding FMJ projectiles are preferred over a 250-grain expanding bullet.
