I have just started playing with my QL program. I first tried my Creedmoor loads and I found QL pretty damn accurate to my bench results using Lab Radar for speed. I only had to tweek my burn rate (ba) less that 1%. When I plugged in all my parameters for my my 6mm Dasher things didnt align at all. In order to get QL to agree with actual data I would have to tweek the ba at least 7%. Its been written that ba should not be altered more than +or- 5%. I wonder if QL does not understand Sierra's new 110smk? I'm out of ideas.
