.264 USA
Overview
.264 USA is a precision cartridge originally designed for the US Army Marksmanship Unit, it is larger than 5.56x45 and slightly smaller than 7.62x51 and fits in AR-15 Actions and magazines allowing for lighter rifles and magazines. Since its original conception it has been turned into a combat cartridge with various loadings for different jobs, additionally following recent trends it utilises a polymer case which allows for a lighter combat loadout than comparible cartridges such as 6.5 Creedmoor.
The round performs similarly to 6.5 Creedmoor but in a smaller package and is considered a 'magnumised' 6.5 Grendel.
EPR
Steel-core Enhanced Performance Round similar to M855A1/M80A1. Multipurpose round with all round performance.
Has red tracer variant.
SOST
SOST Barrier-Blind loading, offering both hollowpoint capabilities as well as soft barrier penetration such as timber, sheet metal and buildings. Poor AP performance despite decent barrier penetration capabilities.
Has red tracer variant.
RRLP
Reduced-Ricochet-Limited-Penetration Frangible designed for urban operations where collateral must be minimised. Fragments heavily within soft tissue offering decent damage. Intentionally poor penetration capabilities due to the frangible nature of the projectile.
OTM
Open-Tip-Match loading optimized for long range combat.
Has red tracer variant.
Subsonic
Designed for stealth operations. It does not produce a supersonic crack and is quieter to enemies making you harder to spot when shooting.
Has green tracer variant, green tracer chosen to mimic Russian barium salt tracers to induce confusion in hostile forces.
Advanced AP
HVIT-APRE
Stats
Note: 343.2 m/s is the subsonic barrier - anything below that is considered subsonic. Subsonic ammunition removes the bullet crack down range making the round better suited to stealth.
Note: these stats are only accurate to TAU-44s modset and vary wildly from default RHS stats.
Ammunition Type | Damage | Bullet Velocity (m/s) | Barrier Penetration | Armor Piercing |
EPR | 10 | 876 | 2.6 | 17 |
SOST | 13.2 | 842 | 4.67 | 8 |
RRLP | 13 | 907 | 0.5 | 4 |
OTM | 11.7 | 988 | 1.6 | 5 |
Subsonic | 11 | 300 | 1.4 | 6 |
ADVAP | 9.4 | 700 | 5.6 | 125 |
HVIT-APRE | 7.4 + 0.08 Explosive Damage @ 1m | 1488 | 11.6 | 425 |
Note: Barrier penetration represents the rounds ability to go through walls and barriers. Armor piercing represents the rounds ability to penetrate body armor plates.
