w-748 is a Super fine ball power. These are just bulk 55 gr. fmj. I used 27.6 gr. 3298 FPS avg ES of 32 because of mixed brass probably. I also incremented up to 28.6 grains and got velocity near 3400 fps, but the groups opened up.



I dialed in my scope and did this out of a open door car window. So it wasn't the steadiest rest for a 5 shot group at 100 yards. But my 24 inch match barrel is a shooter for an AR platform.
