[QUOTE="Schnyd112, post: 1733506, member: 90453"] I would hazard to guess that there is way more variation than you would like to admit. Nothing huge, but a load than chronos 2880-2900 over ten rounds may shoot 2900-2920 the next week. That’s 40 FPS extreme spread over two weeks, unacceptable, but it happens. It’s why I don’t like shooting over a Chrono. Weird things happen and can shake your confidence in a load that shoots great. Angle, time of day, cloud cover, position, it all changes the way velocities are sensed by the chronograph, or does it? Does that mean the load is inconsistent? Or just that there is a weakness in measuring? I can chase numbers all day and all I get is frustrated. But the ability to measure means I do it consistently and have to analyze what I find. I wish I could just shoot and convince myself I pulled a shot that missed. But there is real data that shows there are strange things that happen and I struggle to find an explanation as to why this round was faster/slower than the rest and caused a miss. [/QUOTE]
