The 14.5×114mm HVAP (High Velocity, Armor-Piercing) round is substantially different from the APFSDS round: While APFSDS rounds are sub-calibre, dart-like projectiles with a breakaway sabot surrounding an arrow-like bullet, HVAP rounds are full-bore rounds consisting of a core of high-density, hard material surrounded by a full-bore shell of a lighter material such as an aluminium alloy.
The 14.5×114mm HVAP (high-velocity, armor-piercing) round is an alternate ammunition type from the standard APFSDS, and according to Spartan Jun-A266, is sufficient to "take the hat off" an elite at 2,000 yards. He also implied that they were highly expensive.  


HVAP rounds lose velocity and accuracy at long ranges, giving rifles firing this round an effective range of roughly 1800 metres, considerably less than the 2300 metre ranges of the later-developed, APFSDS-firing SRS99C-S2 and SRS99D-S2 rifles.
{{Conjecture}}
Judging from their designation, these rounds work in the same way as a real-world anti-armor ammunition type typically used in the weapons of 20th century combat vehicles. Also referred to as APCR (armor-piercing composite rigid), but known as HVAP to the military of the United States, the basic design is a core of dense, hard material encapsulated in a conventional full-bore projectile of comparatively lesser durability and density. On impact, the energy of the round is concentrated into the dense core, working to drive it through armor plating. While the function of this round in large-caliber ammunition has largely been overruled by APDS (armor-piercing, discarding-sabot) and APFSDS, many small arms ammunition types designed to be capable of damaging lightly armored vehicles or penetrating body armor make use of the same basic design.<ref>'''Wikipedia''', [https://en.wikipedia.org/wiki/Armor-piercing_shell#Armor-piercing_composite_rigid ''Armor-piercing composite rigid'']</ref>
