Anybody out there necked down the new 375 RUger to 358 yet?

Even Boddington thinks it's a natural way to go.

Sounds a lot like a 358 Norma Mag!!

BIgger...therefore better!?! OVer 100 grains water capacity vs 85 gr for the 358 Norma.

A cartridge virtually identical to what you propose has already been done. It was over 80 years age and was called the .35 Newton. Since the brass for that cartridge has been non-existant for many, many years, the .375 Ruger is a boon to those wanting to shoot the Newton.

Don't know who, but if it can be thought of, it usually has been done virtually before the cartridge has been announced.

This isn't in any way making fun of your question. Being so long ago, many today have no knowledge of the Newton line of cartridges. It was an excellent suggestion. A funny example along similar lines though was the guy that posted on some forum 2-3 years ago. He said he really liked the .243 Winchester, and asked if anyone had ever thought of necking it up to .308!!!!!!

Being a huge fan of the .358 family, I would be in favor of it. My only hope is that they don't shorten the case like they're proposing with their .308 and .338 RCM's. To my mind, these are a terrible idea and they would have been better off leaving the 375 Ruger case as is and necking it down. Shortening it was completely unnecessary.

Just read in Guns and Ammo Hornady is working with Ruger for a 338 RCM, and a 30 RCM, they will be saed off the 375 Ruger case, but made short enough for a Short Action rifle. Sounds like they may have hit a winner with the Old Newton Cartridge. Les

The 358 Ruger is kind of out there. There already is a 35x376 Steyr. Check out my previous reply in the preceeding 8X08 posted thread. Maybe the stalking horse should be one of the M 98 military mausers with a modified Ruger case in 8MM. Sort of a U.S. cousin of the German 8x68 Schuler. Since S.D. flattens out above 8MM, it's looking like a cheap test bed. Is the more than adaquate case wall taper of the 358 Norma, a concession to adrenalin charged chambering of a bolt action, facing down, something, really serious, about some fast food? The parent Ruger case, seems to already have radical shoulders, and a minimum neck, for the 375. Super efficiancy ain't everything. If you need something this big, then you really don't need a jammed and twisted up round, half way into your rifle's chamber. If I had any say at the Ruger outfit, I'd have suggested a Schuler like shoulder and neck with maybe 10% less capacity than the 375 H&H. There was some discussion, at the announcement of the Ruger Hawkeye, about African Hunters, loading down their 375's, a couple of hundred feet per second, for better penetration with the solids available there. The smallish Schuler has a really herky case, and is also a dangerous game rifle, where it's permitted. Streamlined shoulders at 58KCUP or so! A good muzzle brake tames down the 375 RUM, so why not streamline, and low ball, the 375 Ruger, with a lighter rifle, and a good brake? Like, if I had any say in it!
There's got to be better and deeper penetrating solids for 375, than either the 35 or the 8MM bores, anyways. The neato part of this, is that the Hawkeye's stock is welded to the rapid taper of it's barrel. Nobody's going to be able to rechamber and set back a Hawkeye barrel, for a more streamlined and smaller capacity version of the 375 Ruger. It looks like a rebarreling proposition all the way up from 7 MM to maybe the old 475 bores, if that leaves enough shoulder to headspace. Personally, I'd be really surprized, if there's much shoulder left for a 45 cal. in this rimless case. There is now a legitimized 375 x 68S cart. in Europe, and that may be pushing the envelope, considering the 14.5deg. shoulder, and rapid taper of the case walls. A 40+ cal. Schuler may need to be put up, with the flanged version. Now a flanged 375 Ruger, hmmm! Da boys, may still have a way out, with a semi rimmed 450-475.
Ol' George Nonte, published some notes on making rims that crimped into the extraction grooves of rimless cases. But I believe these were only for antiques.
Thanx for this thread.

It would be a real shoulder thumper...maybe a retina shaker, too.

Until I see what RUger is going to do with this case in the next year...I will go back to an old obsession, necking up a 300 WSM to 358.

I have a Savage 358 Win barrel that can be rechambered (1 in 12 twist). That, with a 300 WSM magazine and bolt end will convert my Savage 308 into a 358 WSM (or 35 Sambar as it's also known). With a 3.0" COAL I should be able to do great things w/ 225 and 250 grain bullets.

How would it compare to the 358 STA? I'd think they'd be fairly similar wouldn't they?

SHould be very close...but the 358 STA is longer and skinnier than the Ruger....about 0.35 inch, I think. The Ruger cartridge neatly fits into a regular action.

Didn't they use "Halfmoon Clips" on pistol cartridges??

Hmmmm.. might be an idea on a Martini...

There's some folks already working on it.

No way there's room for that cartridge's name to be stamped on my barrel. I'd have to get a 30" one.
