SLW Barrel Shootout – PPU 75gr Ammo Performance

The sixth ammo we are posting the data for is PPU .223 Rem 75gr HPBT Match. This is one of the least expensive ammo’s on the list and has a wide variety of reviews (both positive and negative). I was interested to see how it performed for us.

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 PPU 75gr shot an average of 2516.5 fps between the 58 shots fired out of the 3 different 16″ barrels we tested. 2 shots of the test were lost when the Chronographs battery died (no fault of the equipment, just the operators lack of attention!) PPU 75gr was about average for velocity when compared to the other ammo’s and had an Averaged Standard Deviation over 6 series of 10 shots of 21.98 FPS which was one of the lower SD’s recorded. 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.

Next are the targets, each barrel shot one 10 round and 2 5 round groups for a total of 60 rounds fired. Barrel 1 had the smallest 5 round group of all the testing with a 1.476 MOA target and a 5 shot group average of 2.350333 MOA averaged between all 6 groups. We had difficulty with this ammo throwing random fliers for no apparent reason. The chrono data (see above) shows no oddities in the extreme spread or standard deviations of any of the series and the shooters didn’t feel they pulled any of the fliers. We also noted that the PPU 75gr had a distinct smell to it when fired, possibly due to the powder type.
