Had good luck with it in a mostly stock SPSV, though not a 308, a 22-250. Pretty good accuracy across my work up loads, with the largest groups at 1.5" and the best being .470" at 100yds. That was first attempt with 50gr vmax and a guess and try on bullet seating, since I can't hit lands. I was very impressed at the vertical of the 6 different groups ranging over 3gr of powder difference. Almost every group was the same spot vertically, though only at 100yds I assume this means a very uniform burn and low ES/SD. No chrono available. Meters pretty good too. Next test will be in the AR.
