If you are waiting on money from me, I guess you won't be making it. We do have some matches here, where Garands, M14's, and AR's get to shoot against each other. They hold them at a little place on the Lake, called Camp Perry. I have seen some fine shooting by some fine guys (USMC, US ARMY, etc), and I have shot next to them. As far as accuracy and range, the M1's and M14's do just fine. At CQB, it would be interesting to say the least...don't forget that the bigger boys can punch though things that the 5.56 can't, and that gives them an edge in jungles, light cover, etc. I have also watched a 5.56 move way off target very fast when the wind kicks up unexpectedly. It seems that ALL factors are a compromise, and the shooter has to be prepared for the limitations of his or her rifle. Yeah, some big guns carry less ammo, and some small caliber guns come up short against cover, etc. But for handling, the skill of the shooter with a larger bore can easily out perform some other lighter cartridge in a gun in a less competent shooters hand. All of the US fighting rifles have good points, and good ergonomics. Put an aimpoint on a scout type mount on an M1 (yeah, they make mounts), and all of a sudden the playing field changes again. Have an optic go dead, or get damaged, and the playing field changes again. Iron sight to iron sight, the accuracy results are probably minimally different, when all ranges and results are averaged. It would be a great test, and even then, it may not be "the final word" on the subject.
