What do you all make of this ladder test for 7mm-08? I've see velocity go down slightly after a peak, but never this drastically, and never seen one stay down as I approached book max. Oddly enough I had some old loads (same components) from another gun at 46.5 grains and they chrono'd about 2910 fps several months back, but the groups weren't great.

Suggestions?
