What would this give you or is there all ready a commercial round that generates the same ballistics?

snow

I would not go so far as to say that there is a commercial round to duplicate any ballistics you might want, but I think that I'm safe in saying that there is a an existing wildcat cartridge that will.

Ray

the ruger is basically the same capacity as an weatherby case... 375 w, or 375HH improved ...
a .308 would be about a 300 webby... (sorry, that one wouldn't do a thing for me)...

but as a .338, yeah, that's nice

jeffe

Seems like it would be very similar to a 300 Dakota or Wby. Both are very fine cartridges if you're looking for that combination of power and trajectory.

See my post to Roger on the 6,5 possibilities. If you did that to the 375 ruger case you would find something very similar to the 30 Newton.

Good observation Ray. You are right about wildcats. There ain't much that we can invent that isn't out there already, or very close to it in preformance. That includes the latest batch of factory short magnums.

But they had to dangle something in front of us to sell new rifles.

Best wishes, Bill

I am not no gun expert but if your talking about a .308 bullet like one in lets say a 30-06 then it would be kinda pointless to do seeing as I remember correctly the .375 Ruger is just a 30-06 case necked up to .375 so really if you necked it down to .308 wouldnt you be just making a 30-06 cartridge?

I have necked down a .375 Ruger to .30...took 2
stages, 1st to .35, then to .30. If you then trim a bit to 2.5", you have basically a .30 Newton!
Which I shoot. Fireform in .30 Newton chamber to
get it exact.
I was curious about the .300 RCM...which should be close to a .30 Newton, but according to the info posted, the case is shorter, about 2.1"...instead
of 2.5 inches. Then on Hornady's web page under their new products...they extol in their advertising of the .300 RCM, the case geometry
design that makes it an efficent case... Well,
duh...Chas Newton did this design in about 1914
with the .30 Newton. Those who do not know their history...but Hornady has some Newton fans...take a proven Newton cartridge, put a new modern name on it...there you go...the wunderbar
of the 2008's.

Tom

You don't remember correctly.
it is NOT a 30-06 case .. that's a 375 whelen

the 30-06 case is .473" nominal .. the HH case is belted, and if straight, would be about .512 (it's actauly .532 on the casebelt) and .510 just infront of the belt..

the ruger is .532 and no belt, so about .530 right in the area the HH case would be .510 ...

roughly, the same capacity as a 375 or 300 weatherby, not the HH versions.

thanks jeff i knew one of them was made from it thanks for correcting me

Actually it is more like a 300WM improved necked up to a 375 Ruger. By the way I stopped in Thunder Bay about 20 years ago on the way to my Moose amd fish hunt. Nice town but no moose.

impossible to make ruger brass from any HH (including 300win) based cases...

you could make hh case, if you had about 10 dies in a set, from ruger case..

the hh is .020" too small around infornt of the belt

Use an 8x68 case.

still doesn't work.. too small.. .510 (ish) vs .532

Yes, Stinger...a 8x68S case works...but when I used
8x68S cases...the brass was so strong, it was a labor of Hercules to form it! I wouldn't do it again, I used German Brass which is tough to form.
The .375 Ruger has nothing to do with a .30-06 case.
The moderator is all wet on this one.

Well looking at Steve's website. He shows the 8x68s as having a .511" rim and .523" base. The Ruger has a .532" rim and base. If those dimensions are correct attempting to use 8x68 brass isn't an approach I would take.

And the Newton case is a few thou smaller than the Ruger case also, rim and head. Close but no cigar.
Similar, very, but not the same.

IMHO, the 375R will be more used as a base for wildcatting than buying rifles for it, much like the 284Win cartridge was forty-what years ago. The manufacturers catalogs for 2008 are out online, and nobody else has jumped on the 375R bandwagon by offering brass, ammunition, or rifles for it...that's got to be killing several posters here...and does not bode well for the future.

I got into this argument before & will again.
RIP talks the talk, but doesn't walk the walk.
Meaning...he hasn't actually done it. The .375
Ruger cases I bought from Hornady measure 0.329"
exactly on the base. The original Western .30 Newton measures 0.326". I agree...not an exact match..but not only close..but entirely practical to make .30 & .35 Newtons from .375 Ruger Brass.
I've done so, and fired the .375 Rugers made into .30 Newton in my original Newtons. Fits just fine. Function is perfect, also Newton bolt. How many Newtons do you have to experiment with? I have them & have done what I've said....003" different makes no difference, as the tolerances aren't that close.
Plus the .375 Ruger case made into a Newton case
gives the same performance as original Newton brass...so where's the beef? A rule of thumb that real gunsmiths know is the thickness of a sheet of typing paper is .004"...and .003" is less than that, the difference of total diameter difference I've miked. So the latitude of the bolt face doesn't mind that.
Best Regards,
Tom

Cut RIP some slack, he's been so busy with the 395 cartridges he about forgets to eat.

I fear that you are confusing the ruger with the steyr, right? the steyr can be (and was) formed from the x64class of cases... but would take ALOT of effort to get an x68 to resize to .501 ... but .522 would slide right into a ruger die..

here a link to ammo guide on the dims of the 8x68
http://ammoguide.com/cgi-bin/ai.cgi?sn=LBxxmEGIGL&catid=346

in the SPECS 8x58 has a casehead of .522, and a rim of .511. In practice, all are slightly smaller, but its about the same.. so lets stick to FACTS.

here's the same on the ruger, from ammoguide
http://ammoguide.com/cgi-bin/ai.cgi?sn=LBxxmEGIGL&catid=525

spec of the 375 ruger case is .532 .. and might measure as small are .529 .. .003 is about normal... but has a rim of .532, again SPEC, and again, .511 is close, but no ceegar.

All wet? yep, at least once a day, and sometimes twice a day on weekends, right after a shower.. Heck, I might even have been stil toweling off when I made that post

Just got a copy of the 2008 Hornady catalog. They introduce two new cartridges. The 300RCM and the 338RCM. They are .375 Ruger Compact Magnum necked down. You have to be quicker than the factory's anymore if you want to do anything new.

those are the 375 ruger, necked down and shortened, as the 375 ruger is not a RCM, as rcm means compacted (shortened) from the 375 ruger case

how about a two bbl take down with 375 ruger necked up to 416 for one and down to 338 for the other.

Tom,

As you have original Newton’s, have you performed chamber castings of your rifles? And if so would you be willing to share the chamber casting dimensions?
