Finally got to the range today. 700x loads at 3.3, 3.5 and 3.7 very small window there from min to max according to the data.
3.5 gave the best accuracy. 3.3 was livable accuracy, 3.7 wow. pretty hot, put a ring at the end of the brass. Primers began to flatten a little.
All loads cycled perfectly even the lowest locked the lug on empty mag. COAL was 1.125 which seems to get me perfect feed results in all my mags new and old.
Will be sticking with 3.5 as it was a 3 inch grouping at 12 yards free standing no rest.
Got 3 lbs of Unique in a trade for some brass just this past week, going to try it out next. 4.5, 5.0 and 5.5 workups. Can't wait.
