30 Cal build need help choosing cartridge

[MudRunner2005]

It takes a Lapua bolt face. Mudrunner what smith did you use for your build? Does he have a reamer?

I used a local smith, and yes he has his own reamer.

Wrong boltface, but my 300 Dakota gets 3,000 with the 215's and 7828ssc. 3,325 with the 185 Berger. If your limited to standard mag boltface get a RUM.....
