SLW Barrel Shootout – PMC 77gr Ammo Performance

The fifth ammo we are posting the data for is PMC .223 Rem 77gr OTM. This ammo was added at the last minute when I was able to purchase a large enough quantity to get good data. PMC isn’t really known for making match ammo so I was curious to see how it performed.

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 PMC 77gr shot an average of 2341.117 fps between the 60 shots fired out of the 3 different 16″ barrels we tested. PMC 77gr had the lowest velocities of all 10 ammo’s tested and an Averaged Standard Deviation over 6 series of 10 shots of 32.13 FPS which was one of the highest SD of all ammo. 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 2 had the smallest 5 round group of all the testing with a .925 MOA target and a 5 shot group average of 1.531833 MOA averaged between all 6 groups. Also worth noting is that barrel 3 shot a very impressive 1.095 MOA 10 round group.
