A Look Back: Historical Roots
The 45-70 Government’s Origins
The genesis of these calibers reveals compelling stories of innovation and adaptation. The 45-70 Government, a black powder cartridge, emerged in the late nineteenth century. It was a product of the United States Army’s desire for a more powerful and effective rifle cartridge to replace the .50-70. The designation 45-70 refers to the bullet’s diameter (.45 inches) and the weight of the black powder charge (70 grains) in the original loading. It was officially adopted in 1873, marking the era of the iconic Springfield Model 1873 “Trapdoor” rifle. This cartridge became the standard issue for the U.S. military, and its impact on the American West was undeniable. It was the weapon of choice for soldiers fighting Native American tribes and also became incredibly popular amongst hunters and settlers. The 45-70’s initial use was characterized by its role in the open plains of the American West. The cartridge’s popularity came from its use on hunts of various types of big game like the buffalo and bear.
The .45 Caliber’s Genesis
In contrast, the .45 caliber story is varied and evolved. It encompasses a range of cartridges developed over the years, with a few particular examples showing great success. One such cartridge that has proven to be a success is the .45 ACP. The .45 Automatic Colt Pistol (.45 ACP) emerged in the early twentieth century, conceived by John Browning. It was designed to meet the U.S. military’s need for a more potent handgun cartridge after observing the relatively poor performance of the .38 Long Colt in the Philippine-American War. The .45 ACP’s history is deeply intertwined with the legendary Colt 1911 pistol, which became the standard sidearm for the U.S. military and saw action in two world wars and other major conflicts. The introduction of .45 ACP revolutionized handgun effectiveness, marking a significant leap in stopping power and reliability. The modern success of the .45 has continued since the military’s introduction, it is still a very popular round today.
Comparing Ballistic Profiles

A detailed understanding of the ballistics provides an essential framework for a proper comparison. These calibers perform uniquely, impacting their effectiveness in different scenarios.
When assessing the physical properties, we see significant differences between the cartridges. The 45-70 cartridge is substantially larger and longer, often featuring a bottleneck shape designed to optimize propellant efficiency. The physical size of the round results in larger case capacity. This is critical for its high amount of propellant, and its capacity to handle heavier bullets. Cartridges like the 45-70 use cases which are built for the use of smokeless powders, enhancing the cartridge’s performance.
The .45 ACP cartridge is considerably smaller, featuring a straight-walled design designed for use in semi-automatic handguns. The .45 ACP has a relatively short case length and is built with reliability and ease of use as priority.
Performance Metrics
Moving on to performance metrics, the 45-70 shines in the realm of raw power. The cartridge delivers significantly higher muzzle energy, particularly with heavier bullet weights. This translates to superior long-range performance and increased energy delivered to the target. Because of its larger size and powder charge, the 45-70 is known for flatter trajectories, which is useful for accurate shooting at greater distances. Effective ranges can easily extend beyond yards, with the ability to take game at farther distances depending on the rifle, load and shooter’s abilities.
The .45 caliber, such as the .45 ACP, prioritizes a different set of strengths. The .45 ACP has a lower muzzle velocity compared to the 45-70. However, it is designed to deliver all its energy efficiently, resulting in a great stopping power at close ranges. The trajectory, compared to the 45-70, is far more curved, which is typical of handgun cartridges. Effective range is typically shorter than the 45-70. This makes it a more effective choice for close-quarters situations. Bullet weight options for both calibers are diverse, ranging from lighter loads designed for target shooting to heavier bullets optimized for terminal performance.
