The 30-30 Winchester is a popular rifle cartridge introduced in 1895 by the Winchester Repeating Arms Company. It was designed for lever-action rifles and is known for its versatility in hunting medium-sized game, such as deer. The cartridge typically uses a 150 or 170 grain bullet and is effective at ranges up to 200 yards. The 30-30 is recognized for its moderate recoil and flat trajectory, making it a favorite among hunters and sport shooters. Its design has remained largely unchanged, and it continues to be widely used in various firearms, including the iconic Winchester Model 94.
