Has anyone tried loading tac for the 6.5? I have a 20inch 1:8 twist rock creek barrel and trying to achieve more fps with 140gr matchkings. Any information would be helpful thanks!

TAC pretty fast for 140's-you'd likely tap pressure ceiling well before velocity peak. Try RL17 for pure speed. TAC is good in 6.5 Grendel, however.
