If you shoot 5.7x28mm ammunition

Posted on May 17, 2016 by Oleg Volk

Take a look at RR Weapon Systems 5.7 loads, especially R37X (0.66″ mushrooms on the right). Loaded to full power (2680fps from 16″ AR57 barrel), accurate for the caliber (2MOA), and good terminal performer (penetrates 12″ of gel).
