The 5.56 is practical accurate to around 600 yards. It's affective to about 300 yards and that's pushing it. The Special Ops guys in Afghanistan found they were getting hits at 300 yards but not always bring them down. They then had 77 grain bullets loaded up in the states and sent over. They started getting good take down hits at 300. I loaded up of the same spec rounds and found the recoil a bit heavier and target impact greater. I fired them through my 16" barrel M4 type.
For all intents the 5.56 is a 300 yard round.
Even with the amount of round carrying load out lower with the 7.62 ,I would rather carry the 7.62 into combat in any situation.

About 4 years ago when I was in the market for an AR style weapon I opted for the 6.8 SPC in the LWRC SPR platform over the 5.56 cartridge. At the time the 6.8 SPC was a little scarce but since is hard to come by. I prefer shooting my M1A and 06 Garand more then I do the 6.8, I guess because most of the AR style rifles all look alike and don't have the character of the vintage rifles.

Well, that's not exactly true. I certainly agree that the M885 cartridge is severely limited beyond 300m. However, the Mk 262 (77 grain BTHP) cartridge will repeatedly hit an E type target at 800m. Service rifle competitors use that same cartridge out to 600 yds and have posted impressive scores. I still like 7.62 rifles a great deal but 5.56 rifles are no longer limited in range as they once were. Ammunition development played a huge part in increasing the effectiveness of 5.56mm rifles. By the way, one of my old friends told me some years ago that when it came to service rifle competition, you either shot an AR type rifle or you got beat with one. Rick

Wasn't it an issue that while the heavier pencil shaped bullets would pierce a helmet at longer ranges the extra stability of the bullet meant that the short range lethality was reduced.

Doug, It was found that the M885 terminal ballistic performance was highly yaw dependent. It could perform well or perform poorly dependent on the yaw angle. Both the Mk 318 and Mk 262 ammo are more effective since they do not have such a high dependency on yaw angle. Rick
