Like all Australian Munitions propellants, the powder used in our 300BLK cartridges features Ballistic Temperature Independence (BTI); a unique major advantage ensuring consistent pressure and velocity – whatever the weather. Used in our factory loaded 300BLK, it is also extremely clean burning, keeping your AR style weapon’s action cleaner for longer.
Australian Munitions’ 300BLK is a versatile round offering four projectiles from a zippy 125gr hunting round up to a subsonic 220gr match round.
Our guys in white coats have developed a new line of ammunition that leaves your barrel at the same high velocity at extreme temperature ranges. No matter if it’s scorching hot or freezing cold, Australian Outback ammunition delivers consistent extreme high velocity and ultra-reliability you demand in all shooting circumstances. For the technically minded, it’s called Ballistic Temperature Independence (BTI). But all you really need to know is Australian Outback ammunition will never let you down.
