50 BMG - Load Data, 50 BMG Reloading, AR15 50 BMG Bolt Action


The .50 BMG or Browning machine gun is a gun cartridge that was developed in the early 20th century. Officially used from 1921 onwards, the. 50 BMG cartridges are used in .50 machine guns as well as sniper and long-range target rifles. The .03-06 rifle cartridges influenced the design of the .50 BMG. There are currently several variants of the .50 BMG. Some of the variants include armor piecing rounds, incendiary rounds, saboted sub caliber rounds, and tracer rounds. For the machine guns, the rounds are connected by metallic links.


The history of the ar15 50BMG bolt action can be traced back to the First World War. It was during this time that John Browning conceptualized the .50 BMG. There was a need for anti-aircraft weapons during the war and .50 BMG fulfilled that requirement. Subsequently, .50 BMG was extensively used during World War II. The M32 Browning machine gun, primarily created as an anti-aircraft weapon, used .50 BMG cartridges. The popularity of the .50 BMG as an anti-aircraft and anti-armored vehicle cartridge began to wane during the 1950’s because several armored utility and personnel carriers were created, which could endure machine gun fires with .50 BMG cartridges.


50BMG reloading takes a bit of practice. There are two primary reloading powders for the .50 BMG available currently. They are the 20N29 and the 24N41. These powders are surface treated and single base. Compared to the N100 powder series, they burn slower with a larger grain size. For developing the .50 BMG loads, the leading ammunition manufacturer Hornady frequently uses a 36″ barrel McMillian rifle with IMI cases and CCI 350 primers. There are a few essential reloading equipment for the .50 BMG. Some of them include the .50 BMG Reloading Press and dies, .50 BMG Powder Measure, and the .50 BMG De-Burr tool.
