Final answer:
The legal magazine capacity for an auto-loading center-fire rifle used for hunting varies depending on the jurisdiction. It can range from 3 to 5 cartridges to having no limit at all, with a common restriction being 10 cartridges across various places.
Step-by-step explanation:
The maximum number of cartridges a magazine can legally hold in an auto-loading center-fire rifle used for hunting varies by jurisdiction. In many places, there are specific regulations that relate to hunting weapons, and these may impose limits on magazine size to promote conservation and safety. In the United States, for example, there are federal and state laws which differ from one another, and the legal magazine capacity can range from as few as 3 to 5 cartridges in some states, particularly for hunting migratory birds, up to no limit at all in others. However, the most common restriction across various jurisdictions tends to be a limit of 10 cartridges for rifles used in hunting. Hunters are responsible for knowing the laws and regulations that apply in their jurisdictions. It's important for hunters to check their state's laws and regulations before hunting.
