5-shot groups have about 55% confidence they are what the stuff will do all the time. And the rounds were not loaded blind to the shooter; he knew which type he was shooting; subconcious issues here.

And we don't know how much of those groups' sizes are cause by human variables. Nor do we know the details of tools and processes used to pass any judgement on them to see if all the good stuff for best accuracy was used and done.

Test again with 20-shot groups so they'll be more meaningful.
