Good point about case volume, & about stopping when you have the velocity wanted. I wanted a minimum of 1350, loaded for that & found dirty burn, so I ramped up 0.5 Gr to get a cleaner burn @ 19.0 so I stopped there. If it ever quits raining I'll chrono the loads, but by calculation & other loads tested that should be about 1400 so I'm happy right there as the extra 0.5 Gr cleaned up a lot.

Here's the brass results I got, weights are the average of 5 cases. The R-P, FED, & "AP" is once-fired, not resized. The Starline is unfired. "B" is the weight of the empty case, "W" is the water contained at 100% capacity.

BRAND................B.........W
R-P (brass)........80.7.....24.4
FED (nickle).......74.6.....25.3
AP (nickle)........76.7.....25.9
StLn (brass).......70.9.....25.4
