.50 BMG Indirect Fire Demonstration - Rex Reviews
Armalite AR-50 equipped with
SWFA SS16X.
Although small arms such as the
.50 BMG are classified as direct fire weapons, the concept of 'indirect fire' may be applicable at long ranges when the target is not in a direct line of sight. The definition of indirect fire is: the aiming and firing a projectile without relying on a direct line of sight between the gun and its target. By this definition, it is possible to take advantage of the parabolic trajectory of these
HTI systems and engage targets partially or completely hidden over a hill. If an obstacle is near enough the max ordinate of the projectile it is possible to strike a target in defilade during if the descending branch of its trajectory is steep enough at that range. This technique can be particular helpful when engaging targets in gentle topography where rolling hills may obscure line of sight. This is why it is important for long range shooters and HTI operators to be aware of their max-ordinate and the angle of descent at different ranges. This data should be kept in a table of secondary functions. For full details, watch the SNIPER

Tracer notes:
These
M48 spotter/tracer projectiles were originally designed to be fired from the M8C Spotting Rifle (a semi-automatic weapon with a 20-round detachable magazine) that was used to spot for the
M40A1 106mm recoilless rifle.
WARNING: The M48 projectile was not originally intended to be loaded into the full pressure .50 BMG cartridges.
The US military specifications for the
M48A2 required a minimum of 1,
500 yard tracer burn time for a MV of only 1,745 fps. This bullet has a very long contour and is filled with pyrotechnics and has only a 0.5 inch long cylindrical lead slug in the center. The back half is filled with tracing compound, the front half is filled with flash and smoke mixture.
NOTE: These bullets were designed for low pressure applications (38,
000 PSI). While the bullet can be fitted into a standard 50 BMG case just fine, it was not designed to handle the full 50 BMG pressure. If you wish to load these projectiles into a 50 BMG case, be sure to safely drop your load down to the original velocity and pressure.
