Just running it through the board.
a .375-235x(or any other premium 235-260gn)from that might be a good step up from the .358win, without having to suffer an overly fat or cumbersome case. Length could be 2.1 ", +/- some.
.358win type fans, what your view???
any idea how much steam we could generate from that setup?


........................................................235x,....................................................250AF.

well,
backing into this.
a 35x284 is 68gr of water
a full length 376 is 80gr of water
and a 375 whelen in 74gr
so, SOMEWHERE betweem those two would be your number... and probably closer to the 74, would be your final answer....

but a 376 fits in a 3.1" action...

At first glance, I really like this one. I think it's a good idea - way ahead of the 338 Federal. I'll give it some more thought. Now, I'm thinking of how to make some dummy rounds to check feeding in a neat little Ruger MK II stainless action I have on the shelf.

You asked how much steam? Well, I dunno for sure, but I'm sure the 350 Rem short Mag fans will be all over this one, comparing notes etc.

Could be an interesting comparison and conversation. I sure hope so.

I shoved some 376 brass into the Ruger short action magazine, and pushed it forward with the bolt just to get some idea of whether it would be a problem or not - the best I can do for now - and it seemed like it would work fine.

When resting in the magazine, the lips of the feed rails over hang enough so that I could see that there would be little chance of the cartridge popping out prematurely, and it centered itself correctly as it moved forward.

It's a workable idea from the standpoint of finding a suitable action. There are many short action Ruger donar actions just waiting on a good idea.

Since that is settled, it would be interesting to speculate (educated guess) about the cartridges performance. Others are more qualified than I on that subject.

I was just fudging around with ideas.When it came up, it turned out pleasing to the eye.
It gives me a nice
-.350-.380 neck,
-choice of more sedate shldr angle than 284win case, and
-no rebated rim.
-no belt
very pleasing overall.
No doubt it would prove useful also.
I just cant take to .375-284win. It looks awkward with its short neck,steep shoulder and rebated rim.
.376shrt idea is not to compete with another cartridge, but to simply be a well proportioned stepup from .358w
Does anyone know what the 235x measures from the tip to uppermost groove??

well this is what i gather...

at 350 rem mag length you will have all things being equal which they never are a 2% decrease in capacity over the 350 rem but an increase in efficiency due to bigger bullet so it is essentialy equal with equal weight bullets to the 350 rem mag performance. confused???

i say use 375-284 reamer and dies but 376 brass since the casehead is about identical and have the nano-rebate and all the extra money you have spend on booz and drugs to come up with the elusive best all around gun.

advantages...one more down than a belted case with maybe a little work for equal performance of the 350 rem but a bigger bullet.

or shorten 376 steyr dies and rechamber to 350 rem length. better yet do a 375 saum as to use longer bullets. or my idea of shortening the 375 ruger to 350 rem mag length to have equal capacity as the wsms due to case dimensions.

or just do a friggn 2" 375 ruger as to use longer bullets and have no rebate on a std. boltface. it will have about 80 grains of capacity (read the same capacity as the 376 steyr...you could call it the 376 fattie). you could use long bullets without issue. now that is a cool cat! the only thing is 3 down instead of four...but if there are no flies on the 376 this is an interesting idea...no bullet length isses, no rebate issues and standard boltface.

i say if you must shorten to 2" do the ruger!

i think i will call it the 375 ruger 2" the 2.17" version i named the ruger short already. headstamp is easy...just add 2" to the 375 ruger headstamp.

I understand.

Have you researched a source for a reamer and dies? Let me know. It's possible that we could work something out, and I share the cost, or just pay you for the use of it, so I can have a chamber cut too. You may want to start with Dave Kiff, Pacific Tool -- etc. for the reamer. I would check first with CH-4D about the dies, then Redding or RCBS next, if CH-4D didn't work out.

I'm rather sure that the neck will have to be turned to the correct thicknes, but thats probably not a big issue. But, I was also thinking it may take more than a FL sizing die to neck that case down. It will probably have to be cut off before sizing, and final trim afer FL sizing. It may have to have a forming die also, so it can be formed in stages. If you are serious about this, find out about that too.

Maybe someone here has enough experience to say whether one pass with FL die will do it or not.

Thanks,

Woodjack,
There is something that I can't avoid thinking about re: this wildcat. What about considering a 9.3mm short? I am bias toward the 9.3mm, and there is something about using a light-for-the-caliber bullet that bothers me - but only a little - namely the 235gr in .375

Another thing - .375 bullets whatever the weight, except 38-55, etc., are mostly made for H&H velocity. Most 9.3mm bullets are made for 9.3x62 velocity. In your wildcat, the standard twist of 12" with a 9.3mm barrel will handle the full spectrum of 9.3 bullets, but the 250 gr probably best.

I think the case capacity will be very close to the 350 Rem Mag case, and that wildcat (9.3) was done before (Sisk), and as I remember it was very close to duplicating the 9.3x62, in a short action.

So, your wildcat could be a neat way of stuffing 9.3x62 performance inside a short action. If that's true, then that's a worthwhile and significant step up from 358W, or 350 RM.

Make the neck exactly the same length as the 9.3x62 neck, maybe the same shoulder angle too.

Think about it -- 9.3x52 just seems right. IMO, it's what J. Cooper should have done in the first place, with his scout rifle. If he had done that, the Steyr cartridge would not have been so obscure these days.

9.5x52 sounds about right too. Take your pick.

KB,
It has certain appeal&character about it.
I dont mind 9.3 bore, but chose .375 to keep things matching in barrel stampings/case headstamp.
a 235x should work fine at the velocities it would run at. I would not plan to use much more than 250@2500.
A Convincing Compact Thumper for wildboar and elk class game in the woods, is what it looks like and all I want.
I think it covers that category admirably.
Im hoping that all one needs is one pass of a FLS die.
If done, it would likely be with .360"+/-neck, maybe 20deg? shld.
I Have not made enquiries yet.
Anyway, its just an idea to kick around and keep on file, no great urgency.

I like the sounds of that.
I notice Im steering away from the fatter cases more and more. I dont mind some of your ideas on the not overly fat .375ruger. They make more sense than .350Rmag,whos belt takes away magazine cap. But leaves wasted space that could otherwise be filled with fuel.
Hence, enter the .375Ruger based "BoomCats" to solve that Issue.

good one...

that is the shortest way to describe my wildcat musings...

to others it makes them go

wadaya think of the 375 ruger 2" boomcat?
use any 375 bullet you want! 376 steyr performance and an easy headstamp.

Aneat little package, but you have to consider case capasity. The 9,3x64 has 87 grs of water, the Steyr about 80. Loosing 7 grains in 4 mm. To reduce it to 52, you can double that loss, so about 14 grs less than 80, and that means 66 grs of water capasity, roughly. Or, on par with the old 9,5x57 MS/.375 Nitro Express. It is not much, but still more than the .375/08.
You might want to measure how long the case really can be with the bullets in question, maybe you can leave the cases at 54mm, every mm counts!

Hello all: I would do something more sensible than being all over the map on this one.
Why not just neck up a .35 Newton case to .375 & basically get a .375 Newton with a 2.5"
cartridge? If wanted (I sent boom stick some examples of .375 Ruger necked to .35 Newton, but he
probably wants to be more complex & esoteric on the subject...)
But the .375 Ruger run through a .35 Newton die can reduce the .375 Ruger length...(trim after
pushing the shoulder back)...then neck back up to .375 with a neck sizer die...
Or..just buy .35 Newton cases from Jamison (supposedly available late next month), neck them up to
.375 & trim to 2.5" or a tad less...
I guess its probably too easy & sensible to have any attraction...
but kidding aside, it would make a very powerful .375 cartridge...and I would think get as much
power as the .375 Ruger with a more sensible length...shorter that is.
Best Regards,
Tom

of all the cases i would have to say the rooger and the steyr case makes the most sense. shortening the steyr by .2" makes some sense but the rooger case will equal the steyr capacity. but does the diff in capacity for you make up the loss of one more down with a little work. hmmmmm...

Bent Fossdal,
Looking at Conley Cart. .358win 225tsx@2550 & .350mag 225tsx2660(sammi length).
No doubt they are the upper limits.

Lets be more moderate and say,That If one can achieve .375-235tsx@2550,
its e-nuffs to satisfy dis black duck.

That is not to say I dont like 9.3x57 Its a thumper that all to often gets unfairly overlooked: 286gn@2330, who could complain?



whitebyson/Tom,
Have you not gathered that this thread is about a rem700sa length ModerateRangeGoodthumpinWoodsCartridge? that is not required or intended to have, NASCARtridgeSmokinUpthebackwheelsin4thGear capability...

If you dont like my .376shrt idea,then just say so!

ithink the 2.1" should be the best compromise of the steyr case...

and when you get bored with that do the 2.1" 375 ruger boomcat.

the 376 woodjack?

Woodjack, I really like your idea, just wanted to make a point of the real advance in case capasity! Loaded to the same preassure as the original Steyr, 2500 fps with a 250 X or A-frame should be easy! Heck, if .375 235tsx at 2550 is your goal, a regular .375-08 is enough! CON is making one, and I can't wait to hear the rapport!

I was refering to the 9,5x57, not 9,3x57, but they are very much the same, also preassure-vice.
