Off-steel groups were apparently due to wind. Watch the mirage changing. What they showed was a single shooter with small round count experimental runs over a distance that's sufficient for non-grass variables to matter. Just doing an experiment doesn't mean your experiment was well put together. Typical result of non-scientifically educated people trying to science. What I see is an average shooter. Nothing against that, I'm an average shooter. I'm pretty good at designing experiments though and this one was not well designed.
