Both actually all three of mine are 10 grain differences and there is occasions where I wish I a five grain increment but it is rare. Flado, and I think I am quoting him correctly, suggested that a 5 grain increment was needed to see an appreciatble difference in velocity, now I suppose with t7 it would be slightly less than 5. In my mind right now I am thinking it would really be hard for me to even pour a 5 grain increment with any reliability. Especially since I am a tapper - somehow I got into a settled powder load - probably came from the days I was reloading with a Lee Loader using spoons...
