I couldnt get the 139 sst to shoot in my gun . try h4350 with any of the bullets you mentioned . my next choice would be either varget or RL15 if neither give the results you are looking for move to 150 grn bullets. i have found in several 7mm08s that 150 grain bullets are much easier to get to shoot at around 2750fps or so . again h4350 and the 150s have worked good for me in the past .
