Maybe I've lived in a ballistic vacuum all my life. But I recently learned of a pretty cool handgun round - 5.7 x 28. I've done a search on this forum and have found nothing for discussion on this round or the FN Five Seven handguns. Does anyone shoot one? With a muzzle velocity of 2100+ FPS and a potential effective range of over 200 yards and maximum range of nearly 2000 yards. Sounds like a fun long range hand gun. Any feedback from those who have one of these or have shot them?
