Re: 6.8 Remington SPC
The 260Rem is a bigger case both longer and alot fatter than the 223(5.56) which the M-16 is built around , it would cost more to make that large of a case work than it would to replace the weapon , their are a few companies that make an AR type rifle based on the larger 308 case , their a good bit larger and heavier.
Personaly I don't see why the Government is considering going with a whole new case , the 223 case is a good base for several larger more powerfull wildcats like the 6mmTCU and 7mmTCU , they could simply neck the 223 up to 6.5mm change the shoulder angle from 23deg to say 30 or 35 , the body taper on the TCU's are already improved but not so far as to lend itself to feeding or extraction problems. Just a few minor chanes to the case and they could call it what ever they want , it sould still feed from the standard mags has the same bolt face would have a good deal more energy and range. loaded with a 107gr MatchKing launched at a velocity of about 2600fps. This round should be infact more effecient than the 223 being that it is not overbored as bad as the 223 is so it would maintain a good velocity even in the shorter 14.5" M-4 guns.
This whole problem in fact would be mostly solved by simply using a better bullet than the crap that the government loads in the 5.56 now.
The United States can't continue to play by the rules that nobody else that we have to go to war with is palying by. If a bullet can be used because it is more accurate then it should be used , if it happens to expand after it hits it target then that is the price they pay for us having to shoot at them [img]images/icons/mad.gif[/img]
