A company by the name of Beck Defense, in collaboration with Devil Dog Arms, and Lancer, has brought out a new cartridge by the name of .510 Beck. The cartridge is a monster round that is fired from an AR rifle, along the lines of an AR10. Similar to other large cartridges that have come out in rest years, the round is designed for hunting. But unlike some of these other rounds, it has a straight walled case. This could allow it to be used in certain states that are very restrictive when it comes to hunting with rifles, while allowing handgun cartridges. Because the case is straight walled, it allows it to be defined as not a rifle cartridge and be used in these restrictive states for hunting. Devil Dog Arms makes the rifles, Beck Defense developed the cartridge, while Lancer makes the straight magazines. The cartridge itself is absolutely massive in size, but has comparable recoil to a 12 gauge shotgun. I’ve posted a video on youtube showing a shooter at SHOT shooting one of these rifles on the line. Bullet weights go from 327 grains to 610 grains. In addition they have a number of different types of bullets that can be loaded in it, including one with a metal sabot surrounding a .308 bullet.
