I have read this whole discussion with great interest. I agree with 366 Torque. If this brass had been available when I made my decision to go with the 366 Alaskan, I would not have used the 338 WM belted brass as the basis. I think the belt is superfluous on anything that can be head spaced on the shoulder, however the 338WM brass was the best thing going, before the 375 Ruger. The 9.3x64 brass has never been an option for me, nor has the Dakota brass, or the 8x68s. I simply don’t want to mess with the bolt face, feed rails or magazine length. Besides, I always thought the belted brass fed good in spite of the belt. The 375 Ruger without the belt just has to feed smoother, plus it will have a little more capacity than the 338 WM brass, just because the brass body is .532 rather than .511.

I am going ahead with the 9.3 wildcat, because it is almost finished. I doubt that I will buy the reamer to open it up and use the Hornady brass, because I already invested in dies, etc. It should be a good wildcat anyway.

I hate to admit this, but as much as I like the 9.3mm, and the 375 H&H, I think this new 375 Ruger is exactly right. This is something that the time for it to happen was way overdue. Of course, it would be exactly right in 9.3mm too, and in my opinion that should have been Ruger’s first choice. Perhaps some of the African regulations had an influence on their decision to go with .375.

I hope it is 2.5" brass, which will make it easy to retrofit any action already set up for the 2.5†belted cartridges, with .532 bolt face. I don’t want to have to deep seat bullets to make the OAL fit the magazine. I have another Ruger action, originally barreled in 300 WM, that I was wondering what I would do with it. Perhaps a 375 Ruger?

What is the max length of a MkII stad. mag box???? I'm hoping the COL of this round will come in under 3.4. Anyone heard?

Jeffe - I guess I was thinking out loud about the high capacity mags ! Seems like a lot guys dislike belted rounds ,RUMS and ect... because they use up mag space ,so I thought a "hi-cap" detachable mag-ala sniper- might work. As to mags"falling out" - US Troops don't seem to have trouble with their mags "falling out" in critical situations.

with the talk of duplicating the 375 h+h in a 20" barrel...are they telegraphing punches with a scout type rifle or some kind of guide model???

they are pretty proud of their scout rifle...maybe they are comming out with it in std length carts

BF can you tell us if these velocitys are going to be Hornadys heavy mag. loads or are these standard velocitys that we can expect from other ammunition companies and also be able to handload. I ask this because they almost match Hornadys 375 H&H loads which are all heavy mag. loads

Has anyone heard of the .375 Breeding (as in RYAN Breeding!)? I first heard of it in the Sept-Oct. 1998 issue of Rifle magazine.

After reading re-reading this article, the .375 Ruger sure resembles the .375 Breeding.

The case dimensions seem right but the velocity is extremely optimistic. s a matter of fact the BS flag should be waved here

I really hope they offer the rifles with open sights, not just a slick barrel - and a barrel band swivel base like some of the Number 1's.

The .375 Breeding is very like the .375 Dakota.

The .375 Breeding is like a .375/404 Jeffery (Saeed) that has lost 1/4" of case body length.

The velocity shown is pie-in-the-sky stuff: it could be true, but only with excessive pressure, and a long barrel.

Expect the UNIQUE .375 Ruger to give 2600 fps with 300 grainers, with no Hornady pie-in-the-sky stuff.

Just dont shoot a Hornady Interbond in it!

This makes very good sense to me.

i guess the best thing about the soon to be 375 ruger ammo is that it comes prepacked with powder...just throw away the cap and stuff with northforks

Nice cartridge.

Lousy bullet.

Boomstick has it figured out!

Hopefully they'll sell new brass and loading dies.

WHEN I can get the specs, I'll be buying a reamer and headspace gages... should be a chamber cleaner for anyone with a 375 taylor. I might even buy the reloading die reamers as well!!

sounds like a neato LITTLE brother to the AR rounds.

jeffe

el jeffe...glad to see you have mourned the loss of the niche of the 376 steyr so well

should be a good 376 steyr chamber cleaner too oops, was that too soon

thanks for leading the way on the 375 ruger for us. you are the lewis and clark of this forum.

good thing for the a.r. rounds is the more volume and in no way can it go to 470! 458 maybe but no simple neck up. the 416 ruger will be a neet round but the 416 a.r. is a true no compromise in terms of power or preasure. the a.r. rounds nich is intrenched firm! jeffe keep up the awesome work

I will keep my .376 Steyr for hunting with 270 grain bullets, and get a .375 Ruger to check it out. My favorite configuration is blue steel with walnut stock, and the sights as previously used on my M77 Mk 1.

jim

Boomy,
remember, I told you the thirties are totally covered!! LOL...

I am not mourning my 376... it won't be changed... but I will slap a 375 Ruger together, as if it is all it's claimed to be, it will fit the same niche as the (hmm, imaginary?) 375 AR... saving me wildcatting it!

jeffe

yeah, you are reeely off the hook for the 375 a.r. unless you chose to show up the ruger...

it still would be great to have the 358 and 9,3 versions... but soon torque will make one and i am sure a bunch will make the 358 as well on the ruger once brass is released.

no need to make one but what do you think of the 416 version of the ruger that i am calling the 416 AMERICAN??? (416-375 ruger bold letters indicates speaking up with pride)

I just received this email from Manson reamers:

Thanks for your inquiry. I apologize for being so long in responding--we looked into the new 375 Ruger extensively and discovered that authoritative specifications will not be available for several months. When they are, reamers and gages for the caliber will be priced as follows: finish reamer--$165.00 (solid pilot) or $195.00 (removable pilot); headspace gages--$50.00 each, plus shipping charges.

I'd chamber two barrels and then sell them should someone want a slightly used reamer and gage. I'd buy the go gage only.

duikerman,
sold..
jeffe

Jeffeosso, Boomstick, RIP and others--

What velocity should I expect from a 358-375 Ruger with 250gr bullets? How about 270gr bullets? In other words, how much faster than the .358 Norma Magnum?

If you already have a .300 Win. Mag. and a .416 Rem, what in-between cartridge would you choose? My thinking was this would fill the gap nicely.

My other alternative that I was thinking would be the .375 Weatherby...to fill the gap betwen a .300 Win. Mag. and the .416 Rem, but I think that there would be lots of overlap on the high-end.

It would be my guess that you'd see about 150 feet/sec improvement in the larger case.

The larger benefit to come with the heavier bullets.

I really think I want one in a 0.410" wildcat ... I even have a donor magnum Ruger MkII standing by Certainly interested to see what the final dimensions of this case are.
Cheers...
Con

Gents,
remember, this is round is "covered" in ackley's books... as the newton line, more or less.

Con,
416 AR?

jeffe,
Do you have the reamers for the AR rounds? Chambered/threaded barrels seem to be forbidden from export out of the USA ... and the courier costs make it unviable. I can get a locally made 0.410 or 0.416 barrel easily enough ... but then I'm stuck for a reamer.
Cheers...
Con

Con,
If you would, send pac-nor an email as ask them about exporting barrels/etc, as they would ahve far more experince than I. Conversly, you can email dave manson and see what he can do for exporting a reamer? I just don't know squat about exporting

jeffe

jeffe,
PacNor themselves are excellent and will ship "steel tubing" anywhere . I know of some barrels currently on order and am waiting to see if they're allowed in.
Might look into the reamers as well as my 'smith usually goes halves.
Luckily the Ruger is in 7mmRemMag so I wouldn't feel any guilt having it pulled apart
Cheers...
Con

long ago, in a far away galaxy...

I had this friend Roger Johnston who was involved with Norma on dimensional specs on the 6BR brass they were going to build eleven-twelve years ago. They needed some 6mm rifle barrels, but Svee-dun wanted about 200% import duty. Rog shipped them 6 barrels marked on the import tag as (you are going to love this Jeffe) "High helix, internally threaded, thick wall tubing.". Like twelve dollars apiece for the "tubing". Perhaps you could "long chamber some of that special spec tubing for our Aussie friend?

just another errant thought,

Rich

I also have the Ruger MkII in 7 Mag just waiting to become a 416 or 404 Ruger.

Yep, I was thinking a deep chambered helix pipe would do the trick... then you are only out dies and a headspace gage!!

the velocities would be almost par to the 375 ruger but a tad less. nothing noticable and at least 100fps over the norma seems reasonable.

who is gunna wildcat this brass and to what caliber???

I have never used a wildcat cartridge, but with this case having a nonrebated rim and .532 bolt face, it might be a good place to start. I think a .416 version would be the most interesting. Man, after looking at this 375 ruger closer and closer, I have a big decision to make. Should I cancel the order i just made on a new 9.3x64 Brenneke and wait to try out the same rifle in Ruger? Decisions ...decisions

Boomy,
based off the ARs, I would tell you that a smaller case (.532 vs .550) on the larger bullets wouldn't do much more exciting than the WSMs, like noveske did withthe 458, and Mann did with te 416 WSM ...

but going DOWN would be excellent.. like the Newton rounds these are copying, the 35, 33, 30, 7, and 22 (wasn't that REALLY a 25?) are exceptional loadings.

jeffe

thanks for the info el jeffe!

yes i think "I" was the first to compare it to the newton line i love the idea of the 35 but it is just so close to the 375. the only advantage is pistol bullets

but being even bigger than the taylor wont it improve the velocity preasure issue and get 400@ 2400 within reasonable preasure???

not as good as the 416 a.r. but a paultry shadow of course...

in years to come the 416-375 ruger (416 AMERICAN) will be more popular than the taylor i predict

I agree and for two reasons. More new builds and at least some Taylors will be rechambered.

Yep!!!! Nothing fancy, just a simple neck down.
I'm hoping it'll be a chamber cleaner!
