A fun thread, what weird wildcat do YOU wish was on the market and popular?

Trashyshoots said:

And what would you like to see it used for? And call it?

I saw a picture of .22 pokey (25acp necked down to 22) and it got me thinking about neat wildcats I wish existed. Lets hear your ideas.

I wish .22 pokey was a thing for magazine forward Olympic styled target pistols.

9mm necked down to .224 for auto loaders, 55gr fmj for range ammo, vmax or gamekings for self defense. Call it the 224 liberty

10mm necked down to .224 but using 80-90 gr bullets. Yes it would be quite long for the grip, but probably do able. I would like it for long distance handgun target shooting, in custom 1911s or maybe mag forward target pistols. Not sure about a name, but 22 autoturbo sounds pretty 80s cheesy. (I like 80s cheese)

Rifle cartridges? Im not big into rifle cartridges to be honest, but im curious what ideas y'all have.View attachment 907086

Your 22-9mm is called a 22tcm. It's not actually a 9mm case, but it's close.
For me, every wildcat I could want is out there. You just have to buy expensive dies and a reamer.
If I had to dream up one. It would be a 10mm necked down to .357.
It should get close to 357 max velocities in a semi auto.

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.

Isn't that essentially 9X25 Dillon?

It appears I'm back to every wildcat I could dream of is already in existence.

We're way past finding a good idea that someone hasn't tried in the last century of wildcatting. Every popular caliber has been necked up/down onto every possible case with a head diameter larger than the caliber.

This is a mature domain; the low-hanging fruit is gone. Future developments will be subtle, marginal improvements (ie 6.5PRC vs 6.5CM vs 6.5Swede) or domain-breaking technos (ie Sig's bimetal high pressure case).

That's not to say it isn't fun; I find cartridge history fascinating! I am past expecting any big improvements prior to my first 3D printed KiloWatt Directed Energy Weapon arriving.

While not a weird wildcat my vote would be for the 22K Hornet.

I like the .277 Wolverine. Would love to see it become a standard cartridge.

And would love to take a ride in a Buick Wildcat.

The .22 Zipperer is a 9x23 necked down. It probably beats the TCM but not by enough to make it important. Many years ago, there was the .22 Goldstein Luger.

220 swift

That had got to be the ugliest bottleneck I've ever seen.

Rimless .357 mag for use in carbines (and pistols, of course). Common bullets. Brass cut down from 223? Use in the AR platform.

The one I always wished would happen and be popular is a 38 or 357 necked down to 32 caliber and shoot a JHP. A .357 would drive that bullet hard and fast, but as high pressure as a .327fed is I doubt it would be much different.

The Remington 7mmBR spawned a family of wildcats from 22BR, 6mmBR, 25BR, 26BR, 27BR and 30BR. Many were later modified into the short/fat cartridges which became popular the last decade or so. The 22BR would make a great varminter round, the 6mmBR is already a world class benchrest round (and in a light rifle would make a great predator round) and the 7mmBR in a carbine would make a great predator/antelope/deer round for 300 yards or so

9mm necked down to .22 manifested itself in the FN 5.7x28 and .22TCM, and rimless .357 is basically .38 Super. i'm unaware of any carbines in .38 Super.

If you want a 9mm necked down to 30 cal, look at the 7.62 Tokarev.

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.

I hunt straight wall areas and like lever actions so I have a bias towards rounds with 1.8” and under case length and can be easily adapted to lever rifles. So a few I would like to see and the reasons why are:

44 Mad Max- Can be chambered in a Marlin 336 and single shots could be converted easily. Bullets for 444 could easily be used. This is a wildcat that exists now.

One I would like to see that I am unaware of existence would be a 35 Remington straightwalled and trimmed to 1.8”. Only .120” case length needs to be trimmed from 35 Rem brass to get to 1.8”. I’m not sure what the bullet diameter would end up at but I’m sure, depending on the case taper, it would be around 41-43 cal. Being able to use 41 or 44 mag bullets would be a plus and a simple rebore and chambering would turn your 35 Rem Marlin 336 into an interesting thumper legal in the straightwall areas.

I had a .358 WSSM in an AR. Crap load of power in a regular AR length. 180 grains at 2,800 IIRC.

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.

Interesting to start with the .308.

This is something I have been mulling around for a few years now. Never had a 35 Rem rifle until recently. Now I have 3.

That would be somewhere around 35 Remington.

Maybe at some point, guys will figure out that a certain amount of powder with a given bullet will result in a given velocity. To a very large degree, it doesn’t matter the name on the head-stamp, the angle of the shoulder, short, long, whatever.

If someone here is not familiar, get a copy of Cartridges of the World.

I used to flip through one of those as a teenager.
The fact that so many were loaded to different maximum pressures skews the numbers though.
