In my earliest manuals , HiVel and HiVel 2 are listed as producing 2700+/- in both the 300 and the 3006. I can't find my lyman #1 right now but Speer #1 from 1954 lists them both at 2700 with the 150g and a almost identical load of hivel. HV 2 is very close to 3031.
Jst my 2 sheckles worth I still have a tiny amount of hivel just for because!!!

the consolidation of the states into one vast republic, sure to be aggressive abroad and despotic at home, will be the certain precursor of that ruin which has overwhelmed all those that have preceded. Robert E Lee
