Mmm, that's a little dissapointing. I wonder too with it being a smaller cartridge and possibly having a higher operating pressure if it would cause extraction problems when the weather gets hot. Same reason why the .416 Rigby is intentionally 'under loaded' to avoid this. Can't believe they release a new rifle and cartridge combo with out the cartridges?? Pure marketing genius!
 
Lack of ammo would of been disappointing, but it wouild of given the writter time to glass bed that wood stock - you just know it's going to split - they always do! I would also loose that front swivel - that is a cut hand waiting to happen. It needs to be moved to the radius of the forend or onto a barrel band.
 
The Rigby was under loaded in the old days because cordite is touchy stuff. Nowadays people load them up to 416 Weatherby velcoities with no problems...other than people wondering why they did it.

"Weatherby factory ammo always gives extraction problems and needs to be down loaded for use in hot conditions."

I'm not disputing the cordite reason, but I also read that deliberatly underloading for reliable extraction is common, easpecially in hotter climates. I also don't see how the .375 Ruger can duplicate or surpass the .375H&H in a smaller case without more pressure. Though with modern powders it may be possible.

I'm pretty sure the 375 Ruger actually has more case capacity than the H&H. It is much fatter, like a shortened 375 Ultra Mag. From what I hear, performance will be like a 375 H&H Improved.

You're right my mistake. Though the article says the same capacity. Will just have to wait for it to come out then.
 
The American forums say 6% more capacity. Yes its practicle but the H&H is way cooler. Maybe someone will come up with a short action 375.
 
Is ammo or brass available yet. Usually the ammo comes first for a while.

Any mention on the cost of the ammo? Prolley crazy expensive!

The .376 Steyr is very interesting, one wonders why Ruger didn't just go with that, apart from have their own name on a cartridge.

Probably because it doens' tmatch 375 H&H velocities, which is sorta a killer of new cartridges..

I wouldn't care if the Ruger doesn't beat the H&H by much, at least you will have l0onger brass life, and you won't eed to fireform, like int he case of many other 375 cartridges out there.

And you don't get the OOOWWW facotr of the 375 RUM or 378 Weatherby.:p

Maybe this is how, :rolleyes: (alot more pressure)


The H&H operates at 62,000+ PSI; considerably more than after dinner gas levels. In estimating how much more pressure would be required to yield another 200 fps, I matched the velocity of Remington factory 375 H&H loads with 75.4 grains of H414, at just about maximum pressure and got 2560 fps. Pressure required to generate an additional 200 fps surpassed the 94,000 PSI mark! I don't care what special powder a factory has blended, the 200 fps more reported for the 375 Ruger, I believe, exists only in the minds and computers of overzealous Ruger friendly writers and Internet rumors. I would be willing to bet the 375 Ruger produces the same, or perhaps a bit less muzzle velocity than the 375 H&H - See Hornady data.

The 375 Ruger comes awfully close to being a 375 Newton. Only about .012" larger in diameter at the base and slightly shorter (.025"). Interesting that a company can stir up interest in a cartridge design from around 1912.
Somebody mentioned necking it to 338. Good plan since it would almost perfectly duplicate the 338 Winchester which is a fine cartridge.
The 375 Ruger is also very close to a beltless 375 Chatfield-Taylor (375/338). I think it would have made as much sense to chamber the rifle for this and the 416 Taylor rather than cooking up a new/old case. In the end it all comes down to marketing anyway. Regards, Bill.
 
Bill's got this one figgered out. Nothing new here. I played with one of these rifles at Christmas in Az. Nice handling (for me) and good workmanship in the one I saw. Good stock finish, bluing, wood/metal fit etc. I have a Ruger Magnum in 416 Rigby that is very similar in appearance. FWIW the folks that had the 375Ruger in stock had no ammo for it either. Mark
ps I found the stainless bolt on the blue rifle to be f'ugly and the front sling swivel should be on the barrel.
