Ran out of my custom .308 136 gn fb bullets so I am switching to Sierra 135 gn fb varminters. This test represents what should be close to 2700 fps loads for each powder used shot from my Bula Defense Systems XM21. Warmup on center of target was with MEN surplus running right around 2800. Then fired 10 rnd groups at 100 yds as marked. I now have a starting point to develop my ladders for each powder. Shot a total of 70 rnds with the 50 on the target for the test. Weather is 42 degrees and raining. Whatta Hobby!
