I did not read the test referred to. I had a book by Thomas, for a while, that seemed to me to be so full of crap that I did not keep it as a reference. I think it was titled Shotgun Facts, even though it didn't contain many, IMO.
However, as quoted, the test above says to me that the faster burning powder produced less true recoil(which was also felt) because there was less of it needed. Right in line with the standard, long accepted formula.
I do remember a similar test in probably Guns and Ammo, some years ago. The conclusion in that test was that the shooters could not detect which shells were loaded with fast burning powder and which contained slow powder. Easy for me to believe, also, as the time difference in the pressure peak betwwen the slowest to the fastest is very tiny.
Still have no idea what Raimey is talking about. No offense, maybe I'm just too iggerant to follow it.
