Australian Munitions (ADI) is bringing their Australian Outback ammunition to the United States. ADI has been making ammunition in Australia for almost 130 years. The new ammunition features ADI’s “Ballistic Temperature Independence” propellant, which like the SMP-842 propellant used in Mk. 262 Mod 1, Mk. 318, and M855A1, reduces the variation in pressure (and thus performance) over a wide range of temperatures (stated in this presentation to be -65.2 degrees F to +176 degrees). BTI propellant is used in the new Australian standard round, the F1A1, a modification of the old F1 (SS109) standard with a new boattail for energy retention and long-range accuracy, and a finer meplat.

Australian Outback ammunition will come in .223 Remington (55gr Sierra BlitzKking and 69gr Sierra MatchKing loads), .308 Winchester (150gr Swift Scirocco II BTS, 165gr Sierra GameKing and 168gr Sierra MatchKing), and .300 Blackout (125gr Woodleigh Protected SP, 144gr AM FMJ, and 125gr HP MatchKing, all with blackened cases).

While due to legal restrictions there is no market in Australia for tactical weapons and ammunition, ADI has further set its sights on the American market with its new ADI MSR (Modern Sporting Rifle) line of ammunition. MSR ammunition also features BTI propellant, and annealed cases. MSR ammunition will come in the same calibers and loads as the Australian Outback line, except for the 150gr Scirocco .308 Winchester load.

ADI’s MSR brochure featured a lighthearted comic specifically targeted at US shooters:
