50BMG 12.7 x 99mm EBB

.50BMG
12.7 x 99mm EBB
Enhanced Barrier Bullet
Enhanced Barrier Bullet
A CNC turned monolithic solid that is
very accurate at all ranges. It is very
effective for targets behind barriers,
with enhanced performance and
predictability. The round is capable
of defeating light to medium armour,
and maintain the original trajectory.
A measured Ballistic Coefficient
of 0.9565 for the .50BMG means
the bullet is supersonic to almost
1800 meters. Allowing reliable
engagement of targets beyond two
kilometres.
Accuracy is assured, even at extended
engagement distances, it will allow
the operator to increase his ballistic
advantage.
