This is update from my last post. I posted two loads that shot the best also chronograph those loads. I did try one other load and chronograph those as well but they didn't shoot as good as other two loads and powder was IMR-7828ssc.
Last weekend I started testing loads at 200/300 yds and I did little adjusting on seating depth and I settled on 56.5gr/IMR-7828ssc @ 2959 fps and yesterday was 5th trip to range and at 200yds group was .973 and 300yd 1.738.
