Two popular rifles for the 30-378 Wby cartridge are the Weatherby Mk V and the Sako M995 (TRG-S) The Sako has been discontinued but they aren't hard to find. I own a 30-378Wby Sako but don't shoot it much. It's kind of like owning a 1960's muscle car. It goes fast but it's difficult to find an application where it's more practical than milder cartridges, besides being expensive to operate.
Both the Weatherby and the Sako are designed as sporter hunting rifles. They really aren't set up for extreme range shooting. Their magazines, barrel lengths, and twist rates aren't designed for heavy VLD bullets. Only you can determine if you want one and whether it should be factory or custom.
