Starting load development on a 300 Super (H&H) I just put together. Started with putting together 3 each of the 180 Accubonds and 180 Partitions with H1000 and H4831SC to see if there is an obvious combo the rifle likes. Also bought some 175 Terminal Ascent but those ended up seated so deep I don't really think that bullet makes sense for the 300 Super.
