The .366-caliber .370 Sako Magnum rounds are loaded with either a 286-grain Barnes Triple-Shock X-Bullet or a 286-grain Nosler Partition bullet. Based on a case that is slightly longer than the .30-06, the new .370 Sako cartridge achieves energy levels comparable to the .375 H&H and provides excellent stopping power on large game at shorter distances. Due to the length of the case, .370 Sako-chambered rifles are built with standard-length actions instead of magnum-length actions. Muzzle velocities of the two new offerings are rated at 2,550 fps with muzzle energies of 4,129 ft-lbs.
