The Norma Dedicated Hunting Tipstrike .270 Winchester 140gr ammunition (MPN: 20169292) is engineered for medium-to-large game hunting where immediate energy transfer and rapid incapacitation are critical. Loaded with a 140-grain (9.1-gram) flat-base polymer-tipped spitzer projectile, this centrefire rifle cartridge achieves a muzzle velocity of 2,986 to 3,084 fps (910 to 940 m/s) and a muzzle energy of 2,771 to 2,957 ft-lbs from a standard 24-inch test barrel. The projectile combines a streamlined polymer tip with an internal mechanical lead-lock jacket, initiating rapid expansion upon impact while preserving core integrity to drive through bone and muscle tissue.

• Terminal Impact Design: Features an aerodynamic polymer tip that initiates rapid expansion alongside a tapered front jacket to deliver devastating hydrostatic shock and short-tracking stops.
• Mechanical Lead-Lock: Built with a thicker, mechanically locked rear jacket to retain core weight and ensure deep penetration through vital zones.
• Aerodynamic Ballistics: Boasts a 0.480 G1 ballistic coefficient and a 0.261 sectional density for a flat trajectory and retained velocity out to medium hunting ranges.
• Quality Components: Loaded in premium boxer-primed, reloadable brass cartridge cases with non-corrosive primers for reliable ignition.

Who is the Norma Tipstrike .270 Winchester 140gr for?

• Deer Hunters (Fallow, Red, Rusa, and Chital): Leverages a 0.480 G1 ballistic coefficient and a 140-grain projectile delivering 1,804 ft-lbs of energy at 300 metres to ensure ethical, broadside vital-zone penetration and flat trajectory across medium-to-large deer species.
• Wild Pig and Boar Hunters: Relies on a muzzle velocity of 2,986–3,084 fps combined with a fast-expanding polymer tip to expend maximum hydrostatic shock upon impact, delivering the instant stopping power needed for heavy feral game.

Less suitable for: Long-range shooting beyond 400 to 500 metres, where a high-BC boat-tail bonded projectile is better suited to resist wind drift, or hunting dangerous, thick-skinned game such as water buffalo and scrub bulls, which requires non-expanding solid copper or heavily bonded deep-penetrating bullets. Not compatible with firearms chambered in .270 WSM or .270 Weatherby Magnum.
