It was completely unremarkable, that is about the best that can be said. I loaded 50 rounds of .260 Remington with 40.0 grains of H4350 and Barnes match burner 140's. twenty five rounds were loaded with CCI 200's picked randomly from the tray. Twenty five were loaded with primers weighed on my A&D 120 to the milligram minus the error rate of plus or minus 1 milligram.
shot five groups of five rounds each @100 yards over a chrono with five mph crosswinds blowing from 9 to 3
average group size for the non weighed groups was .62 inches, smallest group at .51 inches, largest at .76 inches. Group height for all 25 shots was .68
average group size for the weighed primer groups was .6 inches, smallest at .49 inches and the largest was .8 inches. group height for all 25 was .66 inches
random weight velocity SD for all 25 rounds was 20 FPS
sorted weight SD was 23 FPS
To me this rabbit hole is not worth exploring any farther
