I bought a lot of it over the past 2 years, it was mainly fired from a Barrett MRAD and a LMT 18" stainless barrel. My standard load is a hand loaded 175 matchking with 44.1 of 2520. It's technically not as accurate as the 175 match king hand load, but standard deviation on GGG is great for reasonably cost effective higher end factory ammo. The Barrett will print 1 hole at 100 with the hand load, and it able to get extremely close to that with the GGG. I used the GGG at 1,000 yards 3 weeks ago, it did very well.
