I made my own 6 x 47 Lapua from 6.5 x 47 Lapua. Small change, easy and quick to do. I would have just bought 6 x 47 if it was available though. I neck size only, bolt guns only and each box of brass lives with a specific rifle. Once in a while, the necks get annealed and trimmed for OAL, but that's about it. Love Lapua brass, all I use.
