![]() "Ease of manufacture and accuracy were the two most important factors behind this manufacturing method. "There are other solid, turned projectiles we weren't the first," Barrett said. ![]() With a full-value, 10-mph crosswind at 1,000 yards, the bullet drifts just 42 inches and is only 124 inches low at that range with a 500-yard zero. Other startling statistics include 9,517 ft-lbs of energy at the muzzle and 3,710 ft-lbs of juice at 1,000 yards. ![]() 730 and remains supersonic out to 2,150 yards. When launched at 3,300 fps, the Barrett VLD Mk. Machinists took the drawings and started CNC machining projectiles from a 360 brass alloy, which provided the right amount of mass for the projectile's length and diameter. The bullet looked good-properly proportioned-and it sounds cool." "We wanted a bullet around 400 grains that would fly, and that's the caliber that got us there. "The caliber already existed, but our barrel makers had never made. There are quite a few very low drag (VLD) bullets in production, and the Barrett bullet borrowed from them heavily. That would be the result of the right combination of diameter, length, shape, and weight. Barrett's bullet would have to be as aerodynamic as possible and have an extremely high ballistic coefficient. The air moves faster in some places, slower in others-remember Bernoulli's Principle from high school physics-and the bullet becomes less stable. When a bullet starts to slow down to transonic speed-an area of aerodynamic purgatory of sorts-strange things start to happen to the airflow. One of the keys to long-range accuracy is a bullet's ability to stay supersonic. ![]() ![]() The new cartridge would go far beyond just necking down a. Taking a cue from decades of development by benchrest and long-range competitors, Barrett knew he needed an efficient cartridge and bullet, not just a good bullet with more propellant behind it. It turns out that was an easy bill to fill because the cartridge got smaller instead of bigger. The new cartridge would also have to fit into a man-portable rifle in the same class as the current Model 99 or Model 82A1. ![]()
