375 KNOCKOUT

  

The 375 KO is, as its name suggest, a true knockout blow. It's ballistics are superior to any other suppressed round for the AR-15/MSR platform. It leaves the muzzle with 1050 fps and 857 fpe. While the 857 fpe is remarkable enough for a subsonic as it is 50% more energy than the most popular round in the field, the 300 Blackout, but that at 1,000 yards it is still traveling north of 850 fps and has more energy than the 220 grain 300 Blackout load has at the muzzle. The 300 BO shouldn't feel too bad as this is also more energy than a 308 Winchester round loaded with a 168 HPBT has at 1,000 yard. Finally to put it in other terms this round has more energy at 1,000 yards than a standard 230 grain 45 ACP or 158 grain 357 Magnum load has at the muzzle. (internet)
