No pressure signs on anything. I contribute most of that to the most excellent chamber support my Camp Guard 10 provides. I can live with an SD of 15ish.

Going to settle on 9.4 Grains though. Should provide an average of 1215 fps, plus my LnL measure doesn't seem to like 9.5. It will consistently throw 9.4, but it jumps to 9.6 when I adjust it. Quirky I guess.
