Fellow Shooters & Reloaders,
Had a chat with a fellow Shooter the other day and he asked what the difference in compression was "...between .00 such-and-such and inches, because the Ol Time Buff Hunters didn't have a way to measure in .000's did they?"
Well, after scratching my head and trying to answer him with explanations of bullet depth, engraving, measuring powder in the case with a hash mark on a dowel, etc., etc., etc., I got more confused then I was before and said I'd ask the pros here for an easy conversion method and reason why it is the way it is.
OK, have at it!
Best regards and good measuring!
