Tried some more bullet/powder combinations today.
Winners - H4831 - excellent group, working up 0.1 grain at a time, put 7 shots in 1 1/4" group. But, was shooting 6" low at 100 yards with 87 grain bullets. Simple adjusment and that could be fixed though.
Win 760 - Working in 0.1 gr increments and 87 gr Hornady's, very nice group. Ran two strings of 5, under an inch. The bottom of the ladder was 1" low to right on point of aim. Second group of 5, towards to the top of the load group was at POA and 1" higher.
Both with Federal Magnum primers.
