Thread: what have you found that works in 1-7 223

I have 1:7 20" Ranger AR15 that gives 12mm groups at 100 metres with ADI Outback 69 gr HP factory ammo. I have some Sierra 69 gr HP bullets that I intend to use with Benchmark 2 powder, and hope to at least replicate the factory load. Give the 69 grain load a try!
