SLW Barrel Shootout – Federal Gold Medal Match 69gr Ammo Performance

The seventh ammo we are posting the data for is Federal Gold Medal Match 69gr (Also known as FGMM 69gr). This is the first of four 69gr offerings we tested and is the one of the most common ammo’s used for testing AR’s for accuracy. It is one of the most expensive ammo’s we tested as well and I was curious to see if its high price was equaled by high performance.

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 FGMM 69gr shot an average of 2608.214 fps between the 56 shots fired out of the 3 different 16″ barrels we tested. 4 shots of the test were lost when the Chronographs battery died (no fault of the equipment, just the operators lack of attention!) FGMM 69gr had one of the highest average velocities (just behind IMI 77gr and CBC 77gr) and had an Averaged Standard Deviation over 6 series of 10 shots of 17.94 FPS which was one of the lowest 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 0.998 MOA target and a 5 shot group average of 1.250333 MOA averaged between all 6 groups. The ammo performed well and was very consistent.
