6.5 RSAUM6.5 wsm*
*its the 300 wsm necked down to 26 cal
6.5-06 30 degree shoulder*
*it will have the same shoulder as a 6.5 Creedmoor
My imaginary 12x24mm GRD (Grumpy Revolver Dude). 12x24mm GRD is short and fat for quick reliable loading and ejecting from a revolver. It launches big bore 12mm bullets (.475-inch). Max pressure would be a moderate 24,000 psi with a goal of 600-800 ft-lbs of muzzle energy depending on bullet weight. The moderate pressure would keep it easy on your ears, especially when hunting with no ear-pro. Heavy bullets (~400gr) would be sub-sonic at 800-850 fps. Light bullets in the 275 gr range, would approach 1200fps. Case length would be 24mm and would be semi-rimless. The case would use large pistol primers. A large extractor groove to allow the use of very thick (.040-.050 inch thick) robust moonclips (MOONCLIPS RULE!!!) in the large extractor groove. Semi-rimless would also allow the cartridges to head space on the cartridge rim in the absence of moonclips. The Cylinder would be cut much as a cylinder for an rimmed cartridge is cut for moonclips.
Well, maybe not one that will become a factory round. I made this years back when Polish jokes were still PC.. It a round for a Polish Dueling Pistol.

Dang now I even have a neat name for it. Maybe I will have to learn about wildcatting.I have often wanted a 32super.
Alright I've probably been in the house too long might have to go grocery shopping or something before I cook up anything more harebrained.
.358 JDJ is what you're looking for. SSK and Bulberry have info on it.444 marlin necked down to .357. Would be an awesome deer round, but alas, there are soo many good deer rounds now we don't really need any more.
That probably wouldn't back out and tie up the guns as bad as the S&W Model 53 Jet was rumored to do.Take a 22 Jet and blow the case out like a 22 Hornet to K Hornet. It is called the 22 Super Jet, 22 Cotterman, 22 Jet Improved or 22-357 Magnum improved.

Hmmm, at 1.3" you have a .44 Auto Mag...so this would be almost like a .44 Super-Auto Mag... It would make the grip too big for a semi-auto handgun but in a BFR-type handgun or a AR rifle it would thump along nicely.Ye gads that's the hard way around, forming .35Rem from .308 parent brass, but it IS possible.
I'd start with .308, trim 1.8, seat a ~.44 caliber bullet. . . and call it a .454 Casull Rimless.
Elkins45: "The 308 has been necked up to 338 Federal and 358 Winchester. It's been necked down to 7mm-08 and 243. I wish there were a standardized 25 caliber version."
I have wondered that too.
With the .308 and 30-06 relationship you have:
308 Win and 30-06
358 Win and 35 Whelan
7mm-08 and 280 Rem
But...
?? and 25-06
260 Rem and ??
?? and 270 Win
Somebody must have stuck 25 caliber and 270 caliber bullets in a 308 case, and somebody else must have done the same with 6.5 bullets in a 30-06 case.
The 6.5-06 has been around for quite a while. I believe A-Square loads for it. If not now, they used to. I was considering that round when building a rifle almost 20 years ago. Ended up choosing the 6.5x.284.

Isn't that basically what a 7.62x25 Tok is? If so then I'm all in bringing Tok back into modern production pistols and sub guns.How about a this one? A 9mm necked down to .30.
Inexpensive bullets, indeed if we're talking Berry's, but they have a top recommended velocity of 1250 fps and I would think the case capacity of 9mm would push it well above that.How about a this one? A 9mm necked down to .30. We’ll call it the .327 Sig! It’s catchier than 327 Small Block.
Less recoil, in already high capacity pistols.
Using range pick- up cases and inexpensive bullets.
Magnum speeds and penetration, well manner pistols.
Co-developed with @TTv2 .
and I would think the case capacity of 9mm would push it well above that.
Also, I quite like the idea of a high velocity bottleneck that can fit in LCP size pistols that uses a fairly common case in .380 for forming the brass.
