The .45-70 Government cartridge, often shortened to just ".45-70," is a powerful and historically significant rifle round. Its legacy stretches back to the late 19th century, making it one of the oldest centerfire cartridges still in widespread use today. Understanding its history, characteristics, and modern applications is key to appreciating this enduring piece of firearms history.
