You got it, Aaron!!! Lloyd and Jim will agree right along, and actually, deep down, I do too but do not like affording a harem these days. ... felix

Do longer bullets with borderline instability tumble on impact? I could see that as a possible usefulness if sufficiently accurate to the intended distance.
82nd I like your plan.... Just use the onr that is working on that day. LOL
Actually the original AR 15 barrels were 1 in 14 but the army found during cold weather testing that the <193 55 gr load was unstable in cold weather So they set the twist at 1 in 12. A 1 in 9 twist will stabilize the M855 round but some of the other rounds fired by out army need a faster twist at longer ranges. The Army chose a 1 in 7 twist and standardized it as it works with all ammo that could be fired in the M 16 as well as the SAW. Most target shooters have gone to 1 in 8 for match shooting out to 600 yards with up to 80 gr bullets.
