30-30 ammo refers to ammunition used in firearms chambered for the .30-30 Winchester cartridge. It was introduced in 1895 and is commonly used for hunting, particularly in North America. The cartridge features a rimmed, bottleneck design and is commonly loaded with either a soft-point or a hollow-point bullet. The .30-30 cartridge is capable of generating high velocity and significant knock-down power at close ranges, making it suitable for hunting medium-sized game animals such as deer, black bear, and wild boar. The cartridge's popularity has diminished in recent years due to the rise of newer, more powerful hunting cartridges, but it remains a staple among hunters and continues to be a popular choice for those seeking a reliable, affordable, and effective hunting round.
