When they say 8" twist minimum, they want 8" or faster twist... Say 7.5 or 7" twist in this case. Most 1 in 9 barrels will be marginal if they are asking for the 8" twist, especially at lower altitude. Both bullet length AND weight are variables here. My ar shoots some 75-77 grain pills well at 9" twist, but some would be needing an 8" twist, especially the poly tipped ones.
