My go-to load for the 75gr Hrdy BTHP's is:
23.9gr Varget, Lake City brass, 2.25" OAL, Rem 7 1/2 benchrest primers, 1:7.7 twist rate, 24" barrel, AR Platform, 2800 fPS.
Tried many other bullet and powder combinations, nothing beat this one. Sub 1/2 moa accuracy, stabil and supersonic past 1000 yards.
