Aalf, what bullet are you shooting in the 6X47?
I'm shooting pointed Berger 105 Hybrids at 3125. BC is coming in at around .585.
Interestingly, this barrel is a four groove Krieger with the Hybrids, my other 8 twist is a 5R Rock shooting 105 Berger VLD's, and the accuracy load for both barrels is exactly the same using H-4350.
Someone looking to do a 6 mm, this is the answer.
Ever recover a bullet at that range to see if they are opening up at all?
I haven't, but based on the damage, they are opening up some. I did find a piece of lead in one jug, but most likely came from a short shot.
