My RPR in 6.5 staying in the 0.25-0.40 MOA at 100 yards with my current load using Lapua brass, 140 Berger VLD seated 0.020" off the lands, CCI BR4 primers, and Reloder 16 powder. Running 2,821 fps. Consistency and quality is the key to getting the best out of any gun. I've been very impressed with mine. Shot a 4.8" 5 shot group at 1k yards with pretty Gusty winds.
Edit: to be fair, I've not shot the first round of factory ammo in mine, so no clue how it does with factory stuff. I've seen others shoot in the 0.50-0.75 MOA range with factory match stuff.
