Black Hills 223 ammo

I shoot quite a bit of the BH ammo for the longer range stuff in 3-gun. With your twist and distance I would definitely go with the 77smk. The 69 grainer would work but the 77 will do a better job with any wind. I'm assuming this is for an AR, if not, you could absolutely go with a heavier bullet.
