Company reps are not always the best source of information about there products. While the 300 BLK can be shot from 300-440 meters, one musy shoot supersonic ammo, which defeats the primary purpose of the round, and do math regularly which few enjoy.
A 5.56 allows a maximum point blank range of 300 yards. With m193 zeroed at 40 yards bullet trajectory stays within 3.5 inches of line of sight out past 300 yards. Plus, 5.56 ammo is cheaper and has lower recoil.
