Loaded some test rounds for my 6 Creedmoor yesterday. Two charge weights (41.5gr H4350 and 42gr H4350), 105 HVLD. Besides the .5gr difference in the charge weight, both loaded to the same specs. I shot the rounds today and 41.5gr shot faster through the chrono and had a much better ES (5 fps). The 42gr shot about 20 fps slower. Have any of you ever experienced this? Where a slightly lighter charge shot faster than the heavier charge?
