quote Shootall "I haven't a clue" truer words were never spoken.
a few tid-bits from sources I am sure you trust:
Shotgun News, December 5/05 Peter G. Kokalis article-THE M 14 REBORN, Crazy Horse. "Off the bench, the Crazy Horse M14 generated 1.5 to 2 moa groups at 100 yards using match-grade ammunition"
Special Weapons for Military and Police, Gun Buyers Annual #34 Charles Cutshaw article- Enhanced Battle Rifle .308 , Mark 14, Mod O EBR
accuracy, average of 2 5shot groups at 100 yds. Black Hills 168 HPBT 2.25"
Hornady TAP 155AMAX 2.13"
Remington 168 HPBT 2.25"
Small Arms Review, January 2002 Peter G. Kokalis article- Rock 'N Roll Recon Rifle. "with the exception of a few armchair commandos still firing from bunkers in LaLa Land, no one champions the 7.62x51mm NATO battle rifle anymore (and certainly no one who ever really humped one of these brutes and their ammo loads in a real operational area and had a comparative experience with the M16 series)".
I didn't put on a big search for these. Just a few magazines I had laying around. I have nothing current because I have not been out to a magazine rack in 14 months. IF an M14 could be made to outshoot an M16 then military rifle teams would use them. They don't. Case closed.
The M16 is more accurate.
bean field rifles have nothing to do with battle rifles. just as sniper calibers do not support the use of same in a battle rifle. apples and oranges, as usual
