If you where looking at throwing some rounds down range around 600-700yrds with a 16 inch 1/9 twist ar what would be the best ammo? Im not trying to drive nails but would like to have a nice group.

All of my 1/9 uppers shoot the 77gr SMK like a champ. My DSA upper shoots the 77 better than the 69 and 55 grain stuff.

Commercial or hand loaded?

Commercial target ammo would be Black Hills 77 SMK, and Commercial Mil Spec would be IMI 855. There are other and YMMV.

Glen Zediker in his books, suggests that the smaller grain bullets 68/69 will usually be more accurate than the 75/77. However, the wind will blow them around more at long distances. So for shorter long ranges, choose 68/69 and for longer choose 75/77.
