What is .22 50?

It is not clear what is meant by ".22 50" as it could refer to a few different things. Below is some general information about each possibility:

• .22 caliber rifle with a 50 round magazine: There are various rifle models chambered in .22 LR (long rifle), which is a popular and relatively inexpensive cartridge. Some rifles feature a magazine that can hold up to 50 rounds, which is more than the typical 10-round magazine size. These rifles are often used for target shooting, plinking, or small game hunting.
• .22-250 cartridge: This is a centerfire rifle cartridge that was first introduced by Remington in the 1930s. It uses a .22-inch bullet propelled by a high-velocity powder charge, making it a flat-shooting and long-range cartridge. It is powerful enough for varmint and predator hunting, but not suitable for larger game.
• 50 caliber rifle: This refers to a rifle with a barrel diameter of .50 inches. It is typically a large, heavy, and powerful firearm used for long-range shooting, hunting, or military applications. Some popular 50 caliber rifles include the Barrett M82 and the Browning M2. The .50 BMG (Browning Machine Gun) is a cartridge commonly used in these rifles.
