.375 Ruger? What the hell case is that based on?

Looking up some BC's on the hornady website last night, and saw that Hornady has let loose another new cartridge! What is the .375 Ruger case based on, does anyone know? and while it is a 30-06 length action, does it share the same rim diameter etc?

Sounds like it is a larger case than a 30-06. A trade-off between a 376 Steyr or lengthened .284 WW maybe. To get the performance they are claiming, it has to be burning a faster powder with that short barrel to get those values, but compare the shoulders on the case to a .338-06. They are almost identical, so the .375 case appears to be a larger diameter case. Its Hornady, so there may not be a parent case that is easily recognizable. Looks interesting, and I'm sure there will be wildcats from 6-375 all the way to 358-375 and others in less than a year.

I've heard that it may be a 9.3x64 case necked up.

"Guns" Magazine gives these .375 Ruger dimensions...author Jeff John:
head diameter = .529", case length is 2.580"; cartridge length with 270 gr. Bullet = 3.315"

According to the Newton historians and devotees at "Accurate Reloading" this would make the .375 Ruger almost identical to the .375 Gipson-Newton; the .30 or .35 Newton necked up to .375.

If this information is accurate, it might regenerate interest with some of the Newton wildcats. From the ballistic charts I've seen on the net, the .375 Ruger appears to be an excellent cartridge for large and/or dangerous game, with possible applications for long-range hunting with the proper handloads.

It seems very similar to the RWS 8X68s case in dimentions when fire formed it should bring another case to the fore front to be a great 270, 7mm and 30 cal to just rechamber a 270Win, 280Rem or 30-06 and just modify the feed lips of the mag to get magnum balistics from the 308 size boltface.

Looks to be an Ultra mag case chopped and re-shouldered to their desired 30-06 length. Interesting.
