Useful range of 5.56, 1:7 twist, 16" barrel? (loaded question, pun intended)

[QUOTE="FlyFishn1, post: 3087335, member: 127209"] Out of curiosity - what would be the effective/useful range of 5.56 with a 16" 1:7 twist barrel? That is what I have so I am curious on what to expect. That wasn't picked for "long range", per se, but I wanted the faster twist rate in an attempt to get better round stability. I am just not sure what "better" means - IE - at what range will that fall off regardless? As to the "loaded question" part - I realize the above depends highly on the load, also. At this point I am only shooting factory rounds. 62gr M855 is what I prefer at the moment. Looking at reloading it appears I can get up to the 90gr weight range also, but there are some significant drawbacks to it (can't cycle in a semi-auto, low velocity to keep the pressure in spec, etc). So that gets back to the question on useful/effective range. [/QUOTE]
