.416 Barrett

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 a wildcatted .50 BMG case, shortened to 3.27 in from its original length of 3.91 in and necked down to accept a .416 caliber, 398 gr projectile; however, the case dimensions are proprietary. 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.

The Barrett Model 99 was initially the only commercially available rifle using the cartridge. In 2009, Zel Custom Manufacturing released the Tactilite .416 Barrett upper for AR-style rifles Zel Custom Manufacturing curtailed operations in 2018 which was subsumed by another manufacturer, McCutchen Firearms, after the BATFE classified barreled upper assemblies in .50 caliber to be firearms in and of themselves on July 17, 2018. There is now a range of options available from several manufacturers: Noreen Firearms makes a rifle in .416 Barrett, as does Desert Tech, and Barrett now also has a .416 Barrett option for its semi-automatic M82A1. Barrett has also introduced the MRADELR rifle in .416 Barrett.

416 Barrett competition rifles

Today, many competition-driven shooters build custom 416 Barrett rifles with longer barrels ranging from 35-40" to make the most of the 180 grain+ of powder loaded in this cartridge pushing 550 grain solid bullets past 2900 ft/s, significantly higher than the original loading.

This has made the rifle very popular in Extreme Long Range Matches where steel targets are engaged out past 2 miles with specialized optics such as the March Genesis{{cite web

Performance

Barrett 398 gr solid brass boattail spitzer bullet

The use of a lighter, narrower bullet results in a significantly higher muzzle velocity and superior ballistic performance to the .50 BMG, and the .416 Barrett is claimed to retain more energy than the .50 BMG at distances over 1,000 yards. Barrett claims that this cartridge is capable of propelling a 398 gr solid brass boattail spitzer bullet out of the 32 in barrel of a Model 99 single-shot rifle at 960 m/s (3,150 ft/s), giving it a ballistic coefficient of .720, and keeping the projectile supersonic out to 1,737 meters (1,900 yards, ~1.2 miles).

.416 Barrett MSG bullet

Improvement beyond this standard while still using standard .416 Barrett brass seems possible, but the bullets have to be specially designed. An example of such a special .416 Barrett very low drag extreme range bullet is the German CNC manufactured mono-metal 27.5 gram (424 gr) .416 Barrett MSG (G1 BC ≈ 1.103 – this ballistic coefficient (BC) is calculated by its designer, Mr. Lutz Möller, and not proven by Doppler radar measurements). The solid brass .416 Barrett MSG bullet has an overall length of 56 mm and derives its exceptional low drag from a radical LD Haack or Sears-Haack profile in the bullet's nose area. Rifles chambered for this cartridge bullet combination, with a cartridge overall length of 116 mm, have to be equipped with custom made 1016 mm long 279 mm (1:11 in) twist rate barrels to stabilize the .416 Barrett MSG projectiles and attain a projected 1,032 m/s (3,385 ft/s) muzzle velocity.

Legality

A few jurisdictions in the United States, most notably California, New Jersey, as well as a few nations such as Argentina, Austria, Belgium, Italy, Lithuania, Netherlands, and Denmark, as well as the Australian state of Western Australia, |access-date=27 August 2024}} restrict or prohibit civilian ownership of rifles chambered to use the .50 BMG cartridge, but not other calibers (e.g., .416 Barrett).

For California, Section 30905 of the California Penal Code governs exceptions/exclusions to the law: You lawfully possessed the rifle before it was made illegal (i.e., before January 1, 2005), You are the executor or administrator of an estate that lawfully holds such firearms, You engage in lawful target shooting and/or police-approved firearm exhibitions, or You are a non-California resident traveling who is traveling to or from an organized competitive match or league competition that lawfully uses assault weapons.}}
