5-shot groups are consistently 1/2 MOA. I believe there's still more in it. Played around with the seating depth a little, but I can make more precise adjustments to hopefully get her in the 1/3 MOA category.
6.5 Grendel DMR (AR platform I built)
I've also heard that the ELD-M's are doing better than the SMK HPBT's so that will be something I try as well.
I have shot 1/4-1/3 MOA groups, but not consistently enough for me to claim it's repeatable and not just a fluke. Nor am I the best shooter. I'm working on it.
