30 super smith.

So , I came across a unique cartridge. The box says Weatherby crossed out. In its place is 30 super Smith. Inspection of cartridge is a Weatherby 378 case necked down to 30 caliber. Does anyone have any extra info on this cartridge it is in a mark 5. Thanks in advance

I found this pic, but no data on it

Sounds like the modern 30-378 Weatherby?

Yep but without their proprietary radius.

The case appears to be a shade under 2.5", 30/378 Wby case is 2.930".
This case is closer to a 300 Win Mag at 2.62". Would be very interesting to see more info/specs for this cartridge.

I found this load data, in the box with the rifle
