Why might some hunters prefer .45-70 for bear over modern calibers?

Historical Significance

The .45-70 Government cartridge has been used for bear hunting since its introduction in the late 19th century, particularly among trappers and hunters in the western United States. Its effectiveness in taking down large game, including bears, has been well-documented. In fact, it was the standard issue cartridge for the US military’s Krag-Jorgensen rifle during the late 19th and early 20th centuries.

Ballistic Performance

The .45-70 Government produces a significant amount of kinetic energy, with a muzzle velocity of around 1,200 ft/s and a kinetic energy of approximately 2,400 ft-lbs. This level of energy is capable of delivering a devastating blow to a bear, even at close range. Additionally, its flat trajectory and deep penetration make it an effective choice for hunting bears in dense vegetation or at longer ranges.

Practical Considerations

While modern calibers may offer higher muzzle velocities and greater accuracy, they often come with increased recoil and a higher cost per round. In contrast, the .45-70 Government is a relatively low-recoil cartridge that is easy to shoot and maintain. Furthermore, its simplicity and reliability make it an attractive choice for hunters who may be working in rugged terrain or who may not have access to modern amenities.
