Hmmm, interesting results Si. It looks like some of your results cast some doubt over the original theory that downrange chrono testing could be used to pick batches.
There's also some stuff happening that raise other questions - like how a pellet can go through almost the same hole with a difference of 40fps downrange?. That doesn't make any sense to me at the moment.
Top stuff though, thanks for putting in the effort.
Maybe Rob has some theories.. I'm not sure what conclusion to draw from the new data - it's looking like the original theory might not be such a good one after all.
