Choosing the right cartridge for your firearm is crucial, whether you're a seasoned hunter, a competitive shooter, or a dedicated collector. This in-depth comparison analyzes the .45-70 Government and the .308 Winchester, two iconic rounds with distinct strengths and weaknesses. We'll explore their ballistics, applications, and historical context to help you make an informed decision.
