It was not intended to "prove or disprove" anything. It was a quest for information, to see how 6.5 Grendel barrier penetration compares to that of 7.62 M80.
However, I just remembered there was a FutureWeapons episode in which a cinder block was shot with 6.5 Grendel (see 2:30-2:45 of http://www.youtube.com/watch?v=haqXE8nq3io ), and result was virtually the same as I got with 7.62 M80 some years ago.
Stan:
The AMU made a few of these rifles for 3rd ID and maybe the 82nd about seven or eight years ago when the SDM thing was of more interest than today. From my recollection based on communications with the Commander, USAMU at the time, the rifles had to be M-16A4's so if your unit didn't have A-4's it was a automatic No - Go.
The AMU had to stop the effort due to issues concerning the color of the money based on FORSCOM vs USAREC budgetary regulations and some regulations involving exactly what could be done to a TOE issued rifle and what couldn't -- and by whom. The AMU had the regulatory authority to do the transformation but apparently not to do it for anyone except the AMU and not with TOE property of any other unit.
No one got into serious trouble but it ended that part of the DMR. I believe some money was dedicated to it but have not seen a 5.56 DMR issued to any of the SBCT's I have worked with over the years. I have seen the M-14 DMR rifle issued, though.
As for a test. It either supports or does not support a hypothesis. As you said, you wanted to compare. In most cases it would either exceed or not exceed, but in some it may be of importance to determine if they equaled too. Hence getting beaten up over a research question. And, you must state a significance level before you run your tests or your credibility as a researcher will be absolutely trashed. Hence getting beaten up over not stating a level of significance.
