M20B25

The M20B25 is a type of ammunition used in the M20 recoilless rifle, a weapon developed by the United States during World War II. The M20B25 is a high-explosive, fragmentation round designed to be fired from the M20's smoothbore barrel. The ammunition consists of a brass casing containing a propellant charge and a high-explosive fragmentation warhead. The warhead is typically composed of a copper jacket surrounding a core of TNT or other high-explosive material.

The M20B25 round is characterized by its relatively small size and light weight, which makes it suitable for use in the M20's compact and lightweight design. The round is designed to be fired from the M20's smoothbore barrel, which is a departure from the rifled barrels used in many other firearms. The smoothbore design allows for a simpler and more robust weapon, but it also results in a less accurate shot compared to rifled barrels.

The M20B25 round is effective against a variety of targets, including infantry, light armor, and fortifications. Its high-explosive fragmentation warhead is designed to create a large number of small fragments that can cause significant damage to personnel and equipment. The round is also effective against reinforced concrete targets, making it a useful weapon for breaking up fortifications.

The M20B25 round is loaded into the M20 rifle using a dedicated loading tool, which ensures that the round is properly seated in the barrel. The M20 rifle is known for its simplicity and reliability, and the M20B25 round is an important part of its effectiveness. The M20 rifle and its ammunition were widely used by Allied forces during World War II, and they continue to be used in various military and law enforcement applications today.
