Well I am no expert as I just got my 6.5X47 from RBROS about 3 weeks ago. I used the load that Travis developed for me. He says he uses it in most 6.5X47 he builds.
Lapua Brass
42.2 gr of H4350
CCI 450
130 gr Berger
No pressure signs in my gun and is at about 2930 fps. Will shoot in the 2's at 100 yds; with my best group at 700 yds coming in at 2.5". Barrel should settle in closer to 3000 fps after a few more rounds. I have only fired 100 rounds so far. Really enjoy this caliber. 26" Broughton on a Defiance by the way. Good luck with the new rifle.
