Joe;
Thanks for the upgrade. This is much more comprehesible now. These are still very heavy loads, but it was just hard to imagine a load of near 13 drams of powder in a 12ga. the info you provided is greatly appreciated as it gives much more detail on these tests than is often seen, that being in most cases nothing more than the order of placement.
With the greater uniformity of the Whitworth, one can easily see that many might indeed be inclined to give it 1st place.
