The 26 Nosler is based on a the rebated 300 RUM case (.550" base diameter with .534" rim diameter) shortened to 2.590" brass length. The .375 Ruger necked down to .264-caliber would be slightly slimmer, non-rebated, and could be shortened to desired efficiency level, not quite so bad a barrel burner. 6.5 Creedmoor shoulder, neck, throat and bullet atop a necked-down .375 Ruger case: Seems a most beauteous bullet and brass combination. Yep, that cinches it: 6.5mm CREEDMOST Anybody got this urge? My urges are getting smaller calibered as I get older ... Time for my nap now.

Very nice of you Mick! I better leave it full length like you show it. It will still be a little easier on barrels than the .26 Nosler. Riflecrank Internationale Permanente NRA Life Benefactor and Beneficiary https://home.nra.org/ | |||

Yep, a 6.5 Creedmoor-more. I got my pencil and graph paper out. Will do the crude plotting then some sort of computer drawing, more crude than the one above. Figuring to do some dummies by first applying a .300 RCM FL die to the end of a new FL sized .375 Ruger case then run it through a .375 Ruger FL die again before and after running it into a .26 Nosler FL die, then anneal and seat a bullet. Ought to tell something about how long the case grows to be and give some idea of how thick the necks will be in diameter and wall thickness ... Hoping for the least fuss with turning or reaming necks. Then QuickLOAD if I have not slept this one off by then. At www.ammoguide.com, the 6.71 Lazzeroni Phantom has a .530" base diameter and 2.050" brass length, claiming .264-cal/140-grainer at 3250 fps. Also there is a "6.5 Extreme/6.5-300 RCM" shown with .530" base diameter and 2.100" brass length claiming 140-grainer at 3200 fps with a 26" barrel. The 6.5 Creedmost will be about a half inch longer in the brass. Yep, it looks like a rocket. Riflecrank Internationale Permanente NRA Life Benefactor and Beneficiary https://home.nra.org/ | |||

It only takes 3 points in space to specify a wildcat based on a given parent case and pre-set throating: point of shoulder point of neck-1 point of neck-2 Everything else is automatic: The .375 Ruger brass max shoulder diameter is same as that of the .300 RCM, 0.5150" for both. Same 30-degree shoulder angle for both. .375 Ruger case length: 2.580" .300 RCM case length: 2.100" .26 Nosler case length: 2.590" .26 Nosler shoulder diameter: 0.5275", 35-degree angle Superimpose the .375 Ruger and .300 RCM shoulders to see a start at necking down from .375 to .264-caliber bullet: Next, superimpose the .375 Ruger and .26 Nosler with their bases at the bolt face zero distance: Throat will be same as SAAMI 6.5 Creedmoor throat. Twist will be 1:8", and why not 5R rifling, now that I know what that is. Should be good with 160-grain and lighter conventional bullets, and faster than a speeding creedmoor. Maybe custom 160-grain VLD and monometal FN solid would stabilize at the faster revs from the higher velocity? The final length and diameter of the 6.5 Creedmost neck is not decided yet. C.O.L. is going to be somewhere between 3.340" and 3.600". Barrel length: 26" Riflecrank Internationale Permanente NRA Life Benefactor and Beneficiary https://home.nra.org/ | |||

Ha! That from the CAD-CAM Maestro! That is rich! I better get those dummies made and come up with some neck dimensions. Afterall, the 6.5 Creedmost corrects the rebated rim deficiency of the RUM-based .26 Nosler, and is not quite so "inefficient."

WIP, here is the intermediate .308/.375 Ruger: Using Hornady Unique case lube rubbed on with fingers, New .375 Ruger case is first FL sized using .375 Ruger RCBS FL die. Next, neck sizing using .338 Lapua Magnum RCBS FL die, then 300 Lapua Magnum RCBS FL die. Then neck and shoulder sizing in a 300 RCM RCBS FL die set for top of stroke to smooth out neck and shoulder. Works beautifully with four strokes of the press, one for each of four different dies. Now to get from .308/.375 Ruger to .264/.375 Ruger ... but first I better seat a .308 bullet and make some measurements of neck and C.O.L for another wildcat, the .300 Ruger Noncompact Magnum (300 RNM), or the 300 Ruger Magnum: 300 RM Riflecrank Internationale Permanente NRA Life Benefactor and Beneficiary https://home.nra.org/ | |||

Hi Canuck, and thanks for the interest. Two pieces of the 300 Ruger brass (.308/.375 Ruger) have been dummied up. Brass was trimmed to 2.575" to uniform the case mouth, deburred and chamferred. Neck diameter is 0.339" loaded with a .308/200gr Barnes TSX and a .308/220gr Hornady FMJ. C.O.L. on those was 3.395" and 3.307" respectively, and they both work well in a .375 Ruger M77 Hawkeye African. That neck diameter is a happy thing since the 300 RCM has a max brass neck diameter of 0.340". No "dreaded doughnut" detectable. So, I could easily order a reamer for this 300 Ruger wildcat, whenever, didn't know I wanted one of those. I will post a pic of 300 Ruger dummies when I get the dummies done for the 6.5 Creedmost (6.5 Ruger Magnum?). I reckon I will anneal before working the necks anymore. Fingers crossed. Going fine as frog hair so far. Riflecrank Internationale Permanente NRA Life Benefactor and Beneficiary https://home.nra.org/ | |||

There is no question that a 308 Ruger or even a 338 Ruger are about an ideal balance of caliber and capacity for reasonable hunting out to 500 yards, for those who carry their own weapons on their shoulder. But we already have a 300WM and 338WM. I suppose I am waiting for a commercial, SAAMI, 338Ruger before investing the expense and time of for another wildcat development. However, going down to a 6.5mm starts to lose my interest. For me, the natural long-range small caliber "magnum" is none other than the 270Win. Modern bullets like the 110gn TTSX, GSC, (at 3400fps) and 129 LRX (3100fps) allow the 270 to produce magnum hunting trajectories in a plethora of over-the-counter, moderately-price, accurate hunting rifles. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

I decided not to anneal until finished necking down. Worked well without it. .375 >>> .338 >>> .308 >>> .284 >>> .264 4-step neck-down, easy at each step. No brass lost of a dozen pieces done. I will anneal a batch before doing the fire-forming loads. "Anneal after necking down, and before necking up." Neck diameter is a bit thick at 0.297", but that is the same as max for a 26 Nosler, though 6.5 Creedmoor is 0.295" OD neck. Max brass length for the 6.5 Creedmost is 2.590". Max brass length for the 300 Ruger (.308/.375 Ruger) will be 2.580". Both use same headspace gauge as the .375 Ruger, of course. C.O.L. for both cartridges: 3.395" That works through the box magazine of an M77 Hawkeye. Anyway, it should be easy to make-do until custom dies are available, but if you are a settler you won't need to bother at all: "Jebediah is plowing his front yard when his son runs out of the house and asks why they can't have http://www.ispot.tv/ad/AZx6/di...e-settlers-neighbors Riflecrank Internationale Permanente NRA Life Benefactor and Beneficiary https://home.nra.org/ | |||

Since the neck dimensions are going to differ from the 6.5 Creedmoor neck diameter and length, I am going to have to change this wildcat name to simply the 6.5/.375 Ruger. .308/.375 Ruger also will do. So, if Ruger ever adopts these, surely they will call them simply the 6.5 Ruger (or .264 Ruger) and .308 Ruger, in keeping with .375 Ruger and .416 Ruger. That does leave a caliber gap for the .338 Ruger. Anymore than that would be just OCD, like my .395 Ruger Max (excellent cartridge), as well as the easy .423 Ruger that has been done by others, etc. Maybe I will get more than just a ham from Ruger this Xmas.

I'd be interested in a 338 Ruger. But until Ruger sees the light, the 338WinMag covers most needs. I once thought a 270 WSM would be nice, but then I decided that shooting a 110 grain TTSX at 3400 fps was sufficient and the 3500fps of the 270 WSM was really unnecessary. If I get my grandkids a guest rifle it will probably be a 308win with an 18-20" barrel. But having mouthed off my practical restraints, go ahead and enjoy the 6.5 Ruger. Just like animals cannot be shot 'too dead', trajectories cannot be 'too flat'. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

My version of the 6.5/.375 Ruger: Using a caliber-length neck, of thickness arrived at by my method of case forming, and maintaining the 30-degree shoulder, I had to move the shoulder point a bit closer to base. I used a bench-grinder wheel to grind off the base of the 26 & 28 Nosler FL size dies to get that neck on the Ruger case. The extractor groove height at the base of the cartridge may not be exact, that was just eye-balled with a caliper. Use standard .375 Ruger dimensions there. Will need new headspace gauges to go with reamer, and many new barrels for re-barreling often, with this barrel burner. Using 95.0 grains H2O as case capacity, 26" barrel and Retumbo with a 142-grain Nosler AccuBondLR, QuickLoad says over 3400 fps. SAAMI allows the 26 Nosler to go to 65,000 psi-MAX, so the 6.5/.375 Ruger ought to be allowed that also: I do not have RL-50 in my older version of QL, but Retumbo seems to be fast enough.

Yes, your shoulder looks better positioned than the original 2.17" from the base. The original 375Ruger looks like it had some inspiration from the 300WinMag and it needs some push-back when necked down to smaller caliber. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

Thanks for noticing, 416Tanzan. Yes, shoulder point moved from 2.1797" down to 2.1375". Shoulder is 0.0422" closer to base: 1.072mm shorter headspace! Neck length is 0.2640". Looks like the 6.5/.375 Ruger could be loaded down to 6.5-06 external ballistics at a pressure of about 40,000 psi. Nice. Might get a detonation if trying to load it down to 6.5 Creedmoor ballistics. Yep, I am in love with this one. Just to distinguish it from the "26 Terminator" and the one Mick drew up: "6.5/.375 Ruger-Berry." Or "6.5 Rugerby" with "6.5 RB" written for short. Or "6.5 Rugby" with "Six-Five-Rugby" spoken for short. Or any of the above. And the perfect rifles for this cartridge: Any standard length (3.4" box) with a .532" boltface. There are tons of them. Ruger, Winchester, Mauser, Remington, Weatherby, and more ... "Rugerchestermausertonby" is a generic term that comes to mind ... or just "Rugby" rifles for Rugby cartridges. That reamer with a removable pilot could be used with neck and throat reamers for .270 RB, 7mm RB, .308 RB, 8mm RB, .338 RB, .358 RB, and 9.3 RB. Ain't that the berries? .375 and up can just stick with the standard .375 Ruger necked up. Short as their necks are, they are adequate. And I have this pre-existing obsession with the .338 Lapua Magnum case slightly altered from .308 to .510-caliber. So the 6.5 RB is the one that really gets my interest right now. 6.5 RB throat is still incubating, TBA soon.

Here is pencil proof of Mick's SAAMI specs on the .375 Ruger case head: Some more of the SAAMI specs for brass: And the "Ruger Improved Performance" (RIP) cartridges, so far: The 26 RIP is not just a "ripoff" of the 26 Nosler nomenclature. It is a better cartridge. I would rather not settle for a 26 Nosler if I could have a wildcat that will burn barrels almost as quickly. You see, I DO GIVE A RIP for the 26 RIP. R.I.P. certification is pending, so S.A.A.M.I. certification cannot be far off. And then there is the 404 RIP (.423/.416 Rigby Improved Plus) ... I am still waiting on that one to be C.I.P. certified. But is the .423 RIP worthwhile for S.A.A.M.I consideration? That would be the 26 RIP necked up to .423 bullet. That is where the Ruger Improved Performance line overlaps the Rigby Improved Plus line of cartridges. Where RIP-Rugby meets RIP-Rigby. And overlapping both RIP-Rugby and RIP-Rigby clans is the .338 Lapua Magnum wildcat line, from .308 to .510 Caliber, now to be called the "Rest In Peace" line, or the RIP-Lapua Clan. Add a few more oddball wildcats of mine that will simply be scattered about with the "Riflecrank Internationale Permanente" designation, the Non-hyphenated RIP gaggle. Some cartridge designations will have to be changed to fit this scheme. I now summarize for my own hobby interest, and possibly for the adventurous explorers, the pioneers, the few, who refuse to become settlers: RIP-Rugby (Ruger Improved Performance) Family: 26 RIP (.264-caliber) 30 RIP (.308-caliber) 33 RIP (.338-caliber) 39 RIP (.395-caliber aka .395 Ruger Max)) 42 RIP (.423-caliber) RIP-Lapua (Rest In Peace) Family: 370 RIP (.375-caliber) 390 RIP (.395-caliber aka 398 Lapua Magnum) 400 RIP (.408-caliber aka 400 Bateleur) 450 RIP (.458-caliber) 490 RIP (.500-caliber aka 12.7x68mm Magnum) 500 RIP (.510-caliber aka 500 Bateleur) RIP-Rigby (Rigby Improved Plus) Family: .395 RIP (.395-caliber aka .395 Tatanka) .423 RIP (.423-caliber) .510 RIP (.510-caliber aka 500 Mbogo 3-Inch) RIP (Riflecrank Internationale Permanente) Certifiable Orphan (Non-Proprietary) Cartridges: .395 H&H (.395-caliber) 400/.395 Nitro Express 3-Inch Aboriginal (.395-caliber aka 10.03x75R) .375/404 Jeffery Saeed of 2012 (.375-caliber, reverse engineered from Saeed's postings in these forums) 400 Whelen Petrov Berry of 2013 (.411-caliber, Requiescat In Pacem, Michael Petrov) And with that, I will probably never rest in peace.

RIP, Things have been a little slow, I guess my clients are all saving up for April 15th... Nevertheless, more 404 EXP FNB stuff will be happening soon. I've been looking at the Hawk .411 bullets and they make one with a thick jacket that I believe might could stay together at the maximum velocity that the 404 EXP FNB seems capable of, (not that I have a specific need for that). So if what I have been able to achieve, with your help, has been able to make Fred get jiggy in the happy hunting grounds, I consider a well worthwhile effort! I know not the first thing about the certification of which you speak? But I am sure that the RIP line of cartridges are real rippers! | |||

On the 338 Ruger, it would be nice if the versions had a more traditional neck length, say .338" to .34". That could be done be either lengthening the case, requiring the use of Ruger Basic cases, or else pushing the shoulder back, requiring the use of special GO/No-Go gauges. You guys do the work, I'll do the hunting. On the 'forty-ish calibers, don't you see something special in .4 1 6 ? The bullet selection is quite exceptional now that we have a sleek TTSX, a GSC and CEB's of all types. The 416 Rigby sort of started the big bore resurgence of the last thirty years. Well, if the 416 Ruger is necked down to .264" and then necked back to .416", why doesn't a hunter in a plaid shirt just pick up a 416 Ruger? I'm not picking a fight, or dissing anyone's love of tinkering, but I like to put my tinkering where I get something with a significant advantage. The 500 AccRel is a significant advantage. It puts Jeffery ballistics into a standard rifle. Not too shabby. The 338 Ruger puts Weatherby ballistics into a standard rifle and without changing the bolt face. That's a double, 'not too shabby'. I guess I'm just a settler that likes to walk the forests from time to time.

Thanks boom stick, Some good ideas there for me to consider. Is "Buger" pronounced like "bugger" or "booger?" Likewise, is "Bugery" pronounced like "buggery" or "boogery?" As you were. A new system of nomenclature is coming. But "RIP" will definitely be involved in the naming. It may be written either "R.I.P.," "RIP," "Rip," or "rip." Say it either as "are eye pee" or just "rip."

For 416Tanzan: Note that the .375 Ruger has a neck length of only .305" which is only 81% of caliber. The unmodified .375 Ruger case necked down to .338-caliber causes the resulting neck to be only .275" long, 73% of caliber. The SAAMI .416 Ruger has a neck length of 0.339" which is also 81% of caliber, thanks to that 30-degree shoulder hemi-angle, 60-degree shoulder cone angle. The .416 Ruger is a straight neck-up of the .375 Ruger, but with .001" of neck taper. For the .416 Ruger, brass max Neck-1 diameter is .4440", Neck-2 diameter is .4430". For the .375 Ruger, both are .4050". Just a little quirk. But the chamber reamer minimums have .001" neck taper for both .375 Ruger and .416 Ruger. I didn't think the .317" neck length (93% of caliber) on my previous ".338 RIP" above was all that bad. Ditto the .290" neck length (94% of caliber) on the previous ".308 RIP" above. The SAAMI .375 Ruger and .416 Ruger are both 81 percenters. But yes indeed, the .264" neck length (100% of caliber) on the 26 Rip is nice. I would have to get separate chamber reamers and head space gauges for each of the Rip-Ruger wildcats if they all are to have caliber-length necks. Hey, if the .375 Ruger can get by with an 81% of caliber neck length, what is wrong with my 93% and 94% pets. That short neck on the .375 Ruger does add some case capacity. With the 26 Rip, I am happy to go whole hog on the neck length, because it is so over-bore anyway. But I do not feel the need to settle for slavishly making all the necks caliber length. BTW, I do not like the idea of 40-degree and 45-degree shoulder angles. And the Ruger case has only .0085" taper per inch of case body. No room to blow out the shoulder any further, or is there? Note that if you change the .416 Rigby shoulder angle from that horrid 45-degree angle to 20 degrees (with no change in the distance from breech to shoulder), the case capacity is increased, though the neck shortens in doing this. But the .416 Rigby has plenty of neck to spare, and a huge amount of case body taper. The shoulder of the .416 Rigby can easily be widened, as it is on the 500 Mbogo. But the .416 Rigby can be improved by merely making the shoulder angle less, and that alone makes "improvements" for several reasons. When Ackley "improved" a cartridge, he usually had to change 3 things at once: shoulder angle, breech to shoulder distance, and shoulder diameter. Little to improve on the 26 Rip. But how to throat it? ... Riflecrank Internationale Permanente Pet Wildcat Certifying Authority NRA Life Benefactor and Beneficiary https://home.nra.org/ | |||

The 6.5 Creedmoor has a "Weatherbyesque" throat: Parallel-Sided-Free-Bore diameter only .0005" over bullet diameter: 0.2645" Parallel-Sided-Free-Bore length greater than one-half of bullet diameter: 0.1992" Leade Angle: 1.5 degrees. It is gratifying to know that this sort of throat does so well on the 6.5 Creedmoor, and it is just the sort of throat as on most of my wildcats. Now for the 26 Rip ...

.3375 Ruger? That is an easy head stamp conversion from 375 Ruger to a 338 variant. 33RIP-CLN 338 is just too messy 577 BME 3"500 KILL ALL 358 GREMLIN 404-375 *we band of 45-70ers* (Founder) Single Shot Shooters Society S.S.S.S. (Founder) | |||

Canuck, Good idea, I been meaning to update AGAIN for a long time now. BoomStick, Your idea is not worth quoting this time. Thanks for trying to be funny again, I guess? "33RIP-CLN.338" is just a title to mark a cartridge drawing that I will never be using to make a wildcat.

Dave Manson's drawings are the most readable, easy on the eyes. I whited-out some numbers on the ".395 Ruger Max" drawing he did for me, way back when, and wrote in the "26 Ripmoor" specs. Will see if he agrees with those numbers. | |||
