Are you using a expander mandrel?What are people running 108 eld’s at velocity wise with H4350?
I loaded 37.3, 37.5, 37.7, 37.9, 38.1 and shot them today. A few groups were great but had fliers (possibly me) the numbers were also not that great. Lowest SD I was able to achieve was 5.7
velocity was 2940 at 37.3 up to 3040 at 38.1.
29” barrel and Alpha brass.
