[QUOTE="diggler1833, post: 3968400, member: 48072"] Interesting read, thanks for sharing. I like seeing how other people are doing it. That initial "rough seating depth" test is a lot like a game of Battleship. Each barrel will have multiple depths for each bullet where it will shoot lights out...or like garbage. We take shots in the dark until we land on something that is right. I try to visualize it like a wavelength; over the course of .150" you might have four peaks and four valleys (or more, or less)...and multiple points in between where accuracy is average. I've found that the really tight node depths usually run about .005 - .010 long, and that's it. I've since gone to trying to find depths where I can erode .005 and still have an excellent load without having to work up again. That's all assuming you don't mess with the powder charge weight too 😄. [/QUOTE]
