Based on a necked-down .30-06 case, the .25-06 is not as potent as the .257 Wby. Mag., but it remains a favorite of Western hunters due to its combination of high kinetic energy, flat trajectory and tolerable recoil. Consider, for example, the Federal Premium load using a proven game-getter bullet, the 115-gr. Nosler Partition. This cartridge launches the bullet at more than 3,000 fps with 2,400 foot pounds of energy. Zeroed at 200 yards, the bullet drops less than seven inches at 300 yards and still has nearly 1,400 foot pounds of energy.
