[QUOTE="Pdvdh, post: 519078, member: 4191"] It sounds like you're being very careful and methodical with your load development, so I suspect you already know what your next step is. Dry neck lube another 5 rounds and see what kind of ES you get. If it matches the first 5 shots, then you'll know what the story is. If it doesn't match, then it's time for more load development - or another chronograph. With only one chronograph, it's impossible to know if you're getting credible data or not, because you've got nothing to compare to. I run three chronographs concurrently to reduce the odds of being mislead with data from a single chronograph that might be acting up. The odds that more than one will spit out bad data on any single shot fired aren't very high. At the minimum, I can qualify the credibility of any velocity data obtained when the three chronographs aren't in close agreement. Let us know what you conclude if you're able to figure it out.
