Home Forums Hunting & Shooting Express Rifles and Big Bores Only 376 Steyr vs 375 Ruger

376 Steyr
3.075" cartridge overall length
case 2.35"
shoulder 17 degrees
slightly rebated rim of .494" diameter
max pressure is to be 62,000 psi (Steyrs #)
factory fodder is +- 58,000 psi
factory loads 225 and 270 both at +-2600 (published) but around 2550 froma 20" prohunter.
Hodgdon data says that max MV of about 2910 fps can be gotten w/ the 225 grainer and 2388 fps with a 300 grain bullet.

I'd like to know how the two would rounds stack up in direct comparison.
Not if they are popular or avail at walmart. I am not looking for a steyr vs ruger argument but curious about the rounds themselves.

The Steyr is a dead cartridge. Never measured up to the 375 H&H while the Ruger is suppossed to exceed it. Given the traditional looks of the Ruger and expected performance, it might just make it. I certainly plan to give it a whirl and I never entertained the same yearning for the Steyr.

The Steyr was a proprietary cartridge packaged only in Steyr rifles which are considered "non-mainstream" ( read: WEIRD)everywhere except for maybe europe. jorge

i understand that. i am asking how the two rounds measure up heads up.

Well the 375 Ruger so far on paper, bests it by 300 fps? jorge

So the is steyr is dead then the ruger isnt even really born yet.
what load is it supposed to best the steyr by 300 FPS?
i'd like to compare energy difference.
I am curious as to the amount of the same type of powder it takes each respective round to a certain FPS (efficancy), the amount of recoil by a per pound of rifle comparison and the estimated FPS of 225-270 and 300 gr bullets out of the same BBL length.

the Steyr is based off a slightly shortened 9.3x62 case, the Ruger is going to have more case capasity as its a standard length round thats wider(same diameter as the belt on a 7rem mag or related case), case capasity wins, the Ruger can meet the Steyr's performance at much lower pressures or you can load it to normal pressures and it can best it by more than a bit i would think...........comparing these two cases aint rocket science even without having held either in my hand.

hows that work out in a shorter BBL?
is that additional case capacity gonna mean anything without a 24-26" tube to burn it in?

didnt realize the 375H&H needed that length tube, have heard quite a few wack them to 22ish and were quite happy with performance............the Ruger wont best the H&H for case capisity(or if it does not by enough to be meaningful) cant see where a 22 inch barrel will hurt the Ruger

Steyr: 2388 fps with a 300gr bullet (your stats)
Ruger: 2650 fps with a 300gr bullet

That's about 260 fps. Sorry I was off by 40, hence, my question mark in my original post.

Just go to the Africa Forum and you can read lots of posts, some by John Barnsness and an link to the Boddington article. There is no comparison between the two. The Ruger is a vastly superior cartridge. jorge

Superior only in the sense that the 30-06 is superior to the 308.....or the 300 win mag is superior to the 30-06....... increased velocity is the only difference.......by the way, that 2388 fps figure is from a 20" barrel.......what is the barrel length for the Ruger @ 2650 and at what pressure does it run to get there???

No doubt, the Ruger will push the same bullet faster.....even in the short barrel.....but if a person wants a 20" barrel.......just how much does he give up by chosing the 376 over the Ruger round??

If velocity makes a cartridge "vastly superior"......why aren't you shooting a 375 RUM instead of a 375 H&H???

Yes, I own a 376 Steyr.....I also own a 375 H&H and I'm not looking to part with either!

actually Hodgon list the vargets max w/ a 300 @ 2410 from a 24" BBL so we are down to 240 FPS if the 375 ruger speed is also from a 24" BBL. even less it its from a 26".
"no comparison"
thats not entirly correct. if the rugers figures are from a 26" then we could be talking about a difference of less than 150 FPS. i'd say thats a fair place to start comparing. given, as well, that the steyr is shorter 3.07 vs the ruger at, what 3.37 or so?

Ruger figures are from a 23" barrel and runs the same PSI as the H&H.
Look, you are not going to get me to say the Steyr is either comparable to the Ruger or H&H. There is a reason as to why it is a DEAD cartridge. Yes I do believe in higher velocity as a positive component of a hunting bullet. The "vastly superior" was in reference to velocity only, but I guess if you push me, I'd also have to say it is "vastly superior" to the Steyr cartridge that I considered a loser from the start along with that other loser the Scout rifle.

I don't own, nor do I plan to own any rifles with 20" tubes. 22" is my limit. Must be penis-envy.

As to why I am not shooting a RUM, the answer is simple: I don't do Remington rifles, but I do shoot Weatherbys. jorge

A couple of points I'd like to throw out, since I have actually had all the known 375 calibers in my hand, including the Ruger and Steyr, and have shot all except the Ruger.

Ruger/Hornady list the performance of the 375 Ruger as 300 grains at 2660 fps from a 23" barrel. The 375 H&H from my 22.5" barrel will send any 300 grain bullet out at 2550 fps. The 376 Steyr from my 22" barrel is 2495 fps (at 15" from the muzzle). The Steyr isn't any more dead than the 350 Rem mag or the 257 Roberts. It is chambered in many guns every year. The Dakota M97 makes a good platform and will hold three in the magazine. The Steyr was meant to be an in between ballistically and also non belted, smooth feeder. It is based on a shortened 9.3x64 case, (not the 62mm)a perfectly good case, why it was shortened I don't know. I made wildcats by necking the 9.3x64 case up to 375 and down to 338 back in the 1980's. 9.3 bullets were like chicken lips back then.


The 375 Ruger will hold four (4) grains more powder than the 375 H&H (winchester brass).

I don't think the Ruger round is meant to best the H&H but to offer the very well accepted H&H ballistics from a standard length, non belted cartridge. I'm sure it will do that.

Great post, Murphy. I still think the Steyr is a dead cartridge. though. jorge

i am assuming that the 22" tube is custom since i am unaware of that length being ever in production by Steyr. given that i have found that the Steyr BBL's are indede faster than standard BBL's. for instance the hornady #8095 factory load only bests 2510 from a 20" browning and 2560 from a 20" steyr.
in a shorter case, action and overall rifle.
given the whole package bolt throw BBL length recoil ect were do you give the points to the ruger and were to the steyr.
thanks

Yeah! I called Redding twice to get dies for the 376 Steyr cartridge. Once about two weeks after it was introduced and once about a year later and both times they called it a "dead round" with no intentions of making dies for it. I bought RCBS dies and they work fine. I also have a set of RCBS 338/376 Steyr dies for my not so wild cat. That's a more sensible round than the shortened 375. I like to tinker with different cases and make new calibers but when I go hunting I carry the H&H or something bigger.

It is based on a shortened 9.3x64 case, (not the 62mm)a perfectly good case
******************************************

you are correct, sorry its been a long week.........

what are you 376 and 338/06 built on?
curious about the 338/376, BBL length weights and velocities.

If the projections for the Ruger cartridge capacity are true, my guesstimate (from loading my 375 Weatherby) is that the Ruger will push a 270 gr slug to 2900 fps with around 88 gr of 4350 , give or take .

Hodgdon shows the Steyr cartridge OAL length at 3.1 inch making it around a whole 0.2 inch shorter than the Ruger rifle.........big whoop for that...........

Well jorge.....winchester chambered rifles in the RUM line of cartridges.......so there goes your "I don't do Remington" excuse......

The man asked a simple question.....you could have answered it, instead, you tried to turn this into a Steyr bashing thread....WHY???

Nobody said that the 376 Steyr is as fast as the 375 Ruger........

Here is something for you to think about........if you shoot the same animal at 200 yards with the same bullet fired out of a 376 Steyr or a 375 H&H or a 375 Ruger or a 375 RUM.......which one will kill him deader??? <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
