Design
The Barrett .416 cartridge was designed by Chris Barrett, son of Ronnie Barrett, with the help of Pete Forras. The bullet was designed using some NACA low-supersonic-drag equations to design the shape.
The cartridge was designed as an improvement to the .50 BMG cartridge, a common machine-gun and rifle cartridge. It is similar to a wildcatted .50 BMG case, shortened to 3.27 inches (83.06 mm) and necked down to accept a .416 caliber, 398-grain (25.8 g) projectile; It is however of proprietary dimension. Because the two cartridges, the .50 BMG and .416 Barrett, have identical base dimensions, all that is needed to convert a rifle to use one or the other cartridge is a relatively quick barrel swap.
For some time, the only commercially-available rifle in this chambering was the single-shot Barrett Model 99. In August 2009, Zel Custom Manufacturing released the Tactilite .416 Barrett upper for AR-style rifles. Recently the Bohica Arms FAR-50 MK-II bolt-action, single-shot AR-15 upper receiver conversion became also available in .416 Barrett. Noreen rifles makes a rifle in .416 Barrett and other large calibers. Barrett now also chambers its semi-automatic M82A1 in .416 Barrett. Desert Tactical Arms offers a Bull Pup Rifle in .416 Barrett.

Famous quotes containing the word design:
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (1803–1882)
“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (1803–1882)
“I begin with a design for a hearse.
For Christ’s sake not black—
nor white either—and not polished!
Let it be weathered—like a farm wagon—”
—William Carlos Williams (1883–1963)
