The 50. BMG (Browning machine gun) round, originally designed for the M2 Browning heavy machine gun, is used in the Tac-50 and AS50 sniper rifles. 50. BMG is capable of killing in 1 shot or severely injuring a player, down to at least 10 blood. However, 50. BMG does not travel fast, making sniping a tad bit harder for people who like fast bullet speed and low drop. 50. BMG goes best with the Blackwater scope, being able to calculate the bullet drop with the scope mounted, due to the severe bullet drop.
