"They involved the firing of many thousands of cartridges by a team of nine experienced shots of varying build, shooting under a wide variety of conditions with guns of different types, weight and boring. The cartridges were all loaded to give the same velocity to the same shot charge, though by means of powders of various rates of burning. The shooters did not know what they were firing, but were merely required to give marks for recoil. They were unanimous in assigning the lowest recoil to the cartridges with the fastest-burning powder, the dynamical effect of which was checked throughout by electric accelerometers built into the stocks of the guns, and their conclusions have since been widely confirmed." Gough Thomas, "Shotguns and Cartridges for Game and Clays", p. 155.
Well Miller (and anyone else in the audience still paying attention) there--once again, for the 3rd time (twice in this thread and once in the 800X thread) is, to my knowledge, the most complete statement Thomas ever wrote about the tests that were conducted. I can't remember whether I included the entire quote in previous discussions of slow vs fast powders, recoils, the British tests, what Thomas had to say about them etc. What I KNOW is that I have had Thomas' "Gun Book" for a very long time, and it was at some later date (but still years ago) that I acquired "Shotguns and Cartridges", and that's where Thomas elaborates more on the tests than he does in either his "Gun Book" or "Shooting Facts and Fancies".
So, to make this easy, I'll tell you what: If we want to continue this discussion in a fruitful and possibly productive manner, let's stick with focusing on the above quote from Thomas. Because what you remember about what I said on the subject years ago, Miller, is FLAT WRONG. No, I never said anything about only two types of cartridges being used. Thomas never says that, and I've never read anything about the tests in question anywhere except from Thomas, so I don't have any source for that information . . . or rather misinformation as far as I'm concerned. Maybe someone else has something from Thomas they'd like to contribute--via DIRECT QUOTE (as I did, above, citing the source, page, etc). Or maybe someone else (not me!) said something about only two types of cartridges. So, if anyone else has anything else from Thomas--or from any other source--on the IMI tests to which Thomas refers, let's hear it. Maybe someone will come up with the complete 50 page (or whatever) report, which will help answer Mr. Miller's questions about what Thomas wrote. Because other than speculation, I cannot contribute anything more on those tests, or what Thomas said about them, other than what Thomas himself wrote.
