Ruger and Hornady team up to create new Safari rifle and ammunition


(Grand Island, NE) – The engineering expertise of two American shooting sports legends have once again collaborated to create one of the most practical, useful and hard-hitting large and dangerous game cartridges ever — the NEW .375 Ruger.

The cartridge will be similar to the 30-06 in overall length and delivers performance that easily exceeds the 375 H&H — long considered a benchmark cartridge for African big-game hunters. The cartridge was designed from the ground up to provide greater knock-down power with a shorter cartridge. Thanks to optimized case geometry and advances to propellant technology, the Ruger 375 will set new standards for African big game rifles and ammo.

Hornady will produce the Ruger 375 in three different loads: a 270 gr. Spire Point, 300 gr. FMJ-RN (solid) and a newly designed 300 gr. InterBond.

Final specifications will be released as soon as details of production ammunition and rifles are complete. Please watch for further announcements from Hornady and Ruger, and check _

More .375 Ruger Info...
Hello All: I was in contact with Hornady today &
tried to pump them for info on the new .375 Ruger...well, as you would would guess...they are reluctant to let the cat out of the bag with specifics...however, since I am having some custom dies made for my Newton...I pried some info from them. The description they gave was it would be quite similar to a Newton type design in that there would be no belt(boom stick), we know that...but also little body taper...and short,fat case much like the Newton designs. My inquiry was whether I might be able to use the case as a parent case for some of my Newton chamberings...the contact thought that would work very well. As anyone who has read my posts would know, I'm a fervent, raving Newton Fan...Big Time.
Anyway, I know that one of the top guns at Hornady whose input is highly respected is also a Newton fan...and I wonder?...he researches like I do, and there is a "Gipson .375 Cartridge" designed by Gipson many years ago that used a .30 Newton case necked up to .375.
This .375 Newton type...according to Gipson gave very high velocity. And Phil Sharpe once wrote it beat the venerable .375 H&H all to hell as far as performance.
Sooo...I rather suspect that Hornady may have run with a good idea...a Newton type case in a .375...that I know. Whether they borrowed the idea, and made the case just a smigdin different to call it their own rather than a direct copy...but it will be real close, I'd bet dollars to doughnuts its akin a .375 Gipson made up from the .30 Newton case. Also heard that Steve Hornady would probably use it in Africa from which reports would be generated.
In any case...Its a Good Thing! While the .375 H&H is a venerable cartridge, it was designed for the heat resistant cordite powder back then...and a good modern .375 is very welcome.
Best Regards,
Tom

good report

i suspect the body taper to be a tad over 10 thou.

It appears that the rough dimensions for the 375 Ruger will be: length - 2.580", shoulder diameter - .530", head diameter - .532" and body diameter - .550"; so, a slightly rebated rim.

yale...where are you getting this info???

those #s seem wrong.

So, it's a shorter 375AR, sorta.

This thing has the potential of rewriting all the magnums from 7mm to 416 and all it needs is a chamber cleaning. It simply gets rid of the belt by making the case the same diameter as the belt and this increases volume.

I was in process with a classic M-70 conversion to 375 H&H when this news broke and I stoppoed immediately so I don't have to alter the (formerly 338 Win Mag) action.

At least for me this is the most exciting wildcat potential of anything to hit the streets in a long time including the WSMs.

I just want to see the 423 Ruger.

Dear Boomstick:

Information from the horse's mouth. Just called and asked.

Chris

Yale-
any new news?

RG

I noticed that Hornady has some new product announcements on their web site.

I zoomed in on the picture and took some measurements, then assumed the bullet OD was .375 and multiplied through by the fraction.
So here's a SWAG
Rim .502"
Base .524
shoulder .498
neck .400
case length 2.480
to shoulder 2.08
to neck 2.177
this is worth exactly what it cost you. nothing.
Any word on how much the rifles will be?

Lar45: If your measuring is close...it would be very like the old Gipson .375 Cartridge. (made by necking up the .30 or .35 Newton case).
Any child cartridge of the .30 Newton case is a
great one. I'll be interested once the .375 Ruger comes out to see what differences there are, and the .375 Gipson goes back to the late 1930's or 1940's. What's new, is like is said..is not really new.
But it will be a welcomed cartridge for those who like the .375 caliber.

Short necks and longer bullets???????????? Where did my thought process get so screwed up? roger

New news. The latest "Guns" Magazine gives these
.375 Ruger dimensions...author Jeff John, p.38:
head diameter=.529", case length is 2.580"
ctg. length with 270 gr. bullet=3.315"
OK: compare to the .375 Gipson Newton (.30 Newton case necked to .375) head diameter .525" that difference of .004" is the thickness of a sheet of typing paper, very tiny diff. then the case length of the .375 Newton is 2.515"..a difference of .065"
or about 1/16". Which doesn't count for a lot since the diff. is probably neck length & doesn't affect the case capacity. But the Newton has a shoulder dia. of .51" They didn't say what the shoulder diameter of the "New" .375 Ruger was. I'd bet the volumetric capacity of each cartridge is identical, or near identical.
So, you could probably take the new .375 Ruger brass, neck it down to .35 & have a .35 Newton, fireforming with full loads to the slight differences. If not, with full loads, then with a fireforming load. So, at the risk of abrading someone's oh so sensitive, sensitivity: The .375 Ruger probably came about of someone at Ruger doing their homework & finding the highly regarded .375 Newton-Gipson, and used it, at least close enough, to use the idea. Whereas, it seems to me, wildcatters should be the class of gunners who should do their homework to develop cartridges...but apparently from the reaction likened to a kid in the candy store, wants it just given to them on a platter. Then rejoice so...but Gipson had this cartridge back in the 40's...some 60+ years ago!
Hornady also told me that I could very likely just neck down the .375 Ruger to make new Newton cartridges....35 Newton or .30 Newton...so that confirms my speech here that the new development is oh so much a .30 or .35 Newton necked up to .375, like Gipson did many moons ago.
It will be interesting to see, when Marc Jamison makes the new Newton brass to see how many great wildcats will come of the .30 Newton case.
Best Regards,
Tom

While that's good info, the base diameter is incorrect. it is .532 rim and .532 case

jeffe

i sure hope it is .532...

if it isnt that would be enough diff for another maker to go with a 532 and not have a lawsuit i.m.o.

if it is newtonesque in dimensions it would give rise to more newtons being around (good thing)

So will a regular long action work for this round? I mean can we see a long action Savage chambered for it at some point. I guess what I driving at is the price???? That 375 Newton, was it chambered in regular bolt rifles?

Will it fit down the feed of a 98 Mauser???

Wow, Jeffe, pretty sure of that are you?
I would assume not having read the article that ol' Jeff had a case in his hands when he wrote that. Did you when you did?
:P
Besides, not like you to argue over .003" when talking about *nominal* specs anyway!
Sounds like they've breathed new life into the Newton rounds, which is all good in my book.

BB,
the fella I got the measurements from works at Hornady....

yeah, so i am fairly certain!!!!

jeffe

What is the comparison between the 375 Ruger and the various Dakota cartridges ?

jeffeosso...yeah, that's the measurement I heard
too. .532". I was quoting the magazine author...don't know where he got his info from...but he quoted the .529", so I repeated it so with his credits. Still, pretty close.
Best Regards,
Tom

Yes, the difference between .529" and .532" may just be the difference between min and max, or actual measured product and nominal max brass spec. which is what we want:

Max brass spec of .532" rim and .532" base/head diameter is the only thing that makes sense.

hey Ripper,

keep peace in the family...just say spin!

Hi all . gumboot here. I think the Newton was great. should have stuck around to meet up with X bullets. This 375 Ruger looks perfact as long as we can hand load for it and they first make it in an ALASKAN version with green stainless steel every thing and a brown synthetic stock with the 2nd under barrel recoil lug bedded to the foreend. With a set of shallow V express sights and a quarter rib to mount a scout scope and a 13" LOP. In short a rifle I don,t need to fix so it will work . The brass looks like it will make a nice 411 or 416 . Preformanes wise it will need to do 2700 fps w/270 gr s.p.
