One of my hunting buddies of 30+ years had Bevan King barrel him up a 9.3 on the 300 Win Mag case this past summer. It is built on SAKO with one of Bevan's fine barrels, 26" long.
He was going to build a 9.3X64, but as muledeer mentioned above, it was no more expensive to do the wildcat, and 300 brass is everywhere. He has been mickey-mousing brass using a 338 Win die for the first step, and then 358 Norma mag sizing die with a 9.3 expander in it for the second.
CH is making a die set for him. They told him it is not the first set they have made for this wildcat, however it will still be six months delivery.
He gets way over 2800 fps with 286 gr Hornadys, and 2900 with Speer 270s using H4350 in the 26" barrel, and the rifle groups consistently around three inches at 200 meters.
He calls it his canoe gun!
It will be interesting to see what it will do, once he gets a proper die set
