Had to re-work my load for 1x fired brass. Dropped 40 fps using the same load that I used in new brass. Went from 26.9 to 27.3 grains to get similar velocity. Still getting single digit SD. Might try some Varget.

Mine also lost velocity after the initial firing. I rolled with it and ended up at 2775 in a 24" bartlein.
