Im on another gun related site and this seems to be hashed and re-hashed more times than I can count. We all know that the 5.56 has some serious issues stopping a man who is bent on killing you. That said the AR platform is my baby. I love the modularity of it and I happen to own 13 of them in different configurations. Many have attributed the lack of stopping power to the current m855 ammo being like an ice pick going through human flesh. The original twist rate of the barrel was 1-14 if I am correct. Out of neccesity it was changed to 1-7 to accomidate more chemicals in tracer rounds. Longer bullets need a faster twist rate to stabilize. The current ammo could not effectively hold enough of the glow stuff to give the tracer rounds effective range. Thus the current ammo we have. The platform was originally designed with the 1-14 twist so it would barely stabilize in flight and cause major tissue damage due to the tumbling effect upon impact. This is less likely to happen with a bullet that is incredibly stable (1-7) than it was with the original 1-14 twist. Then we have revisions in bullet design that have come about as of late. Im talking about the 77gr mk262 ammo that is being issued in small amounts to our boys over there. Ive had experience with both and neither is a shining example of the ideal round for combat. Both have tradeoffs that I would like soldiers not to have to make. The 77gr rounds are more effective at killing the enemy for sure but penetration of that ammo can be stopped effectively by drywall it would seem. Likewise the M855 ammo can penetrate moreso that the 262 but I have seen and heard of more than one instance where an enemy has absorbed upwards of half a mag and didnt go down. Both are definite problems but both kill the enemy. Just not as well as I think most would like to see. So what would you gentleman like to see in regards to the caliber we are issued. All Ideas are welcome but I prefer it to be from people with actual experience in the field of which I speak. Thank you in advance.
