Meet the .950 caliber JDJ, each round costs about $40 and weighs over half a pound.
With a muzzle energy of 38,700 ft-lbs, the .950 destroys almost anything it touches (your good old 5.56x45mm has at most 1,300 ft-lbs for comparison). The only reason this ammunition isn’t restricted as a “destructive device” is because it has a “sporting use” exception.
Good luck keeping your shoulder in socket! Click here to see some another big round!
