I don't know if it's bar or good that I haven't given up on them yet.
I'm sure you've already gone there, but with the 6.5x47 you may want to try Varget with the 140's. It's worked better for me than H4350. I'm on my second barrel in a row that hammers with exactly 37.1 gr Varget and 140 Berger hybrids (same smith and reamer, different barrel brand).
Hammers = Three to five shot groups (1's - 3's) at 100 yards being the norm; prone, bipod, rear bag. Occasional 'bad' groups (likely either me, conditions aka me, or the barrel needs cleaned aka me also
