This chart indicates 24.5 grs. of TAC.

I've had great success using Re15 and AA2520.

Using LC brass, Rem Bench Rest Primers, and 23.5 grs. of AA2520, I'm hitting an average of 2765 FPS and get well under MOA, best so far for a 5-round group in my 18" WOA SPR was .575" at 100 and 1.5" at 300. Same load went .446" for 5 shots in my 20"BHW SPR.
