    The Scott Satterlee method for building an accurate load starts with 1.5 gn below max and goes up .2 gn for each of 10 loads. Anybody know how that math works out? For one of my loads, 43 gn is max. That'd put the start point at 41.5 and then .7, .9, 42.1, .3, .5, .7, .9, 43.1, and finally 43.3 - above the max. I slept at a Holiday Inn Express once but I can't figure this math out!

    Doing his method you use the chronograph and look for flat spots (or nodes) in the speed. After that you can shoot groups to tweak jump if need be.

    I understand that. I just don’t get where 10 increments of .2 gn = 1.5 gn.

    I've never paid attention to the 10 increments part just set my limits and used the .2 on short action rounds.
