SLW Barrel Shootout – Australian Outback 69gr Ammo Performance

The ninth ammo we are posting the data for is Australian Outback 69gr HPBT Sierra MatchKing. Australian Outback isn’t as well known in the United States but this ammo is sure to turn some heads at around $0.55 a round (if you can find it in stock!). I was excited to see how it performed as it is a very budget friendly round.

All Chrono data was measured by a LabRadar Doppler Chronograph and the data was pulled from the strings saved to its SD card

All target measurements were done with OnTarget Precision Calculator software.


 

The Australian Outback 69gr shot an average of 2529.226667 fps between the 60 shots fired. Australian Outback 69gr had an Average Velocity about exactly in the center of the pack and had an Averaged Standard Deviation over 6 series of 10 shots of 28.99 FPS which was one of the highest SD’s recorded in testing. The graph below shows the shot to shot velocity of each string and also the average of each string at the end (data point 11). Further down is the raw data that this graph was generated from.
