LGF,
Thanks for that data. It looks suspiciously like there might be a severe outlier in the first set of hard wad data. You might check the individual datums for that. Very curious stuff. I don't know what SDs should be for shotguns. BP rifles, should have SD in the single digits pretty easily and I don't see why shotguns should be any different. Unfortunately, my chrony went tits-up this summer for some reason.
