Data is messy, one of my rules. The test groups are larger than the historical groups, but the historical groups were messy. 9 of the 10 groups weren't much larger than history. The 7th group was me, yanking twice. The 8.2 gr groups did not show up low all the time. Of the 10 groups, 4 or 5 groups had one of the two widest = 8.2 gr. Of the 20 sets of widest apart shots, 4 or 5? were 8.2 gr shots, wouldn't we expect each shot, #1 for ex., to be a widest apart shot about 4 or 5? times.
A test like this has no short declarative sentence results, except perhaps "Groups of 4@ 8.5 gr and 1 @ 8.2 gr aren't wildly inaccurate."
As always, more data is needed. Perhaps more analysis would help, I'd be happy to send a bigger clearer picture of the target to anyone.
