What is FMJBT Ammunition?
Federal Military Jacketed Ballistics Tactical (FMJBT) ammunition is a popular choice among shooters and ballistics enthusiasts. In this article, we’ll explore the definition, history, benefits, and differences between FMJBT and other types of ammunition.
Definition: What is FMJBT Ammo?
FMJBT ammunition is a specialized type of full-metal jacketed (FMJ) cartridge that combines the terminal ballistics of a non-expanding bullet with the consistent accuracy and feeding behavior of a ball bullet. The "B" stands for "ball", referring to the round profile of the bullet. FMJBT bullets have a distinctive design, with a hardened, drawn-brass core, encased in a reduced-lead-to-bismuth- ot (RLBT) cup, and covered by a thin layer of drawn-copper or steel wire.
History
FMJBT ammunition is not a new development in the world of ballistics. The concept dates back to the early 19th century, when armorers began experimenting with methods to improve the penetration of muzzle-loading muskets. The first commercial introduction of FMJBT technology came in the early 1980s, during the development of the Ruger 10/22 competition rifle. The purpose of FMJBT design was to create an cartridge that would provide accurate shots while maintaining the velocity retention, which was lost while going through the steel airfoil.
Benefits: Why Choose FMJBT Ammunition?
Nowadays, FMJBT is widely used by a broad range of shooters including tactical, competitive, military and law enforcement communities worldwide, due to the outstanding ballistics and consistent in a variety of guns: bolt action, semi-auto handguns and rifles. Many professionals and enthusiasts are raving about the unique balance between penetration and accuracy that FMJBT possesses.
Here are the prominent advantages of FMJBT over other types of rounds:
• Superb Penetration: Due to its unique design, with reduced lead-based-to-bismuth technology, FMJBT remains stable and intact despite traversing various distances from long-range shots to rapid follow-up shots. A major advantage in many field environments.
• Extensive Accuracy: Consistently accurate, reliable function with minimal fouling means, and a very controlled expanding rate, especially considering for long-range targets to engage.
• Minimum Disruption: Low rimfire muzzle to ensure a low initial trajectory, and for accuracy within the first shot fired
• Multi-task ammunition: For hunters or law enforcement agencies interested in using a single brand or caliber for different disciplines. FMJ BT technology allows for shooting fast multiple shots, yet can stop a threat as its ability is not to be fully disintegrated when using multiple shots**.
