Though shrapnel rounds are now rarely used, apart from the beehive munitions, there are other modern rounds, that use, or have used, the shrapnel principle. The DM 111 20 mm cannon round used for close range air defense, the flechette-filled 40 mm HVCC (40 x 53 mm HV grenade), the 35 mm cannon (35 × 228 mm) AHEAD ammunition (152 x 3.3 g tungsten cylinders), RWM Schweiz 30 × 173 mm air-bursting munition, five-inch shotgun projectile (KE-ET) and possibly more. Also, many modern armies have canister shot ammunition for tank and artillery guns, the XM1028 round for the 120 mm M256 tank gun being one example (approx 1150 tungsten balls at 1,400 m/s).
