I was thinking today, how cool would it be to make a wildcat cartridge? Not only this, but have it become a regualr, mass-produced cartridge by some ammo manufacturer (like federal).

If I were to make a wildcat cartridge, I would either make a .243 necked down to .22 (essentially a 22-250 but with a slightly larger case), or a 30-30 necked down to .243 (probably wouldn't be too good, but for curiousity's sake I'd like to see how well it performed. I would like those and a .308 necked up to 8mm (may have been done?).

Any input on 'my' wildcat cartridges?

Please feel free to add your own ;).

Neck .50 BMG down to .17 or .223. Put about a 3' barrel on it... I assume the bullets would be ripped apart :evil:

I honestly don't see a need for many wildcats aside from building something unique, which is the draw. Most commercial loads cover the bases very well, although many popular calibers started as wildcats

i would neck down a .45-70 to .30 say like a 150 gr

that baby would fly i be with the propper rifling it would be like a lazer too
 
You know, a .30-30 necked down to 6mm or 7mm could be kind of interesting - Only problem I'd really see standing in the way would be finding flatnose bullets... Conversely, I wonder if a .35 caliber .30-30 would work...
 
Sorry fellas, they've all been done before, each and every one of them. Even the 50BMG necked down to .22 caliber, it was called the eargesplittenloudenboomer. See P.O. Ackleys books and learn all about it.
 
Yup there aren't many wildcats you can think of that haven't been done already. There are several .22/.243's out there. 7mm Waters is .30-30 necked down.
So how about oddball pistol wildcats. I want .32acp necked down to .25 cal!!
 
I'd like to see something like a .50 AE necked down to .30 (7.62x25 bullets). I'd also like to see something completely insane. I'm thinking taking the 30mm Brass from an A-10 Warthog necked down to .17 caliber.
 
I would like to see some type of captive piston cartridge. Where the cartridge contains all of the expanding gasses from the propellant and allows the gun to be completely silent without using a suppressor:D
 
There is a company that is working on a 7.62x25 necked down to a .22. So you can buy a CZ52, install the new barrel, and have a poor man's FN 5.7.I didn't say I would do it, but a .22 bullet in a solid copper projectile would probably be very much so armor piercing considering that the 7.62x25 already will punch through a lot.

I've long suspected that rimmed cartridges are/would be inherently more accurate than rimless cartridges because of the better headspace control.

In a bolt rifle built for target or varmint shooting, something with larger case capacity than a .22 Hornet might be my snowy winter night's dream, and something in .22 or 6 mm based on the rimmed .30-30 case would fulfill my fantasies. (If you could get lightly-jacketed, say, 60-70 gr. BTHPs for the 6mm with a slow twist, say 1-12 or 1-14, rifling.)

And when I turn over in this winter night's dream, I wouldn't mind seeing a .257 or 270 diameter bullet come out of a case based on the .303 British rimmed cartridge for longer range hunting.
 
I can get you J4-jacketed 62 grain flatbase 6mms...

Much lighter, and they don't work all that well, accuracy wise, at least out of the PPC...

And inside 500 or so yards, a boattail isn't going to add much, and in fact takes away from intrinsic accuracy.
 
"...and in fact takes away from intrinsic accuracy..."

I won't argue that too forcefully, but I believe differences in accuracy might well be due to whether they are hollow point boat tails or "FMJ" boat tails. Hollow points, I am told, can be more uniformly produced than "FMJs."

It would seem the major effect on accuracy come from uniformity of the bullets' bases rather than their noses.

Or so I'm told. But I wouldn't argue that forcefully. OK, so I give up, let's make the 6mm .30-30 or .22 .30-30 with your preferred bullets, flat based hollow points.

See? I'm easy to get along with.

Even that's been done by the russians

And apparently now there is a .32acp necked down to .25 caliber a .25 NAA

there isn't a wildcat you could come up with that someone hasn't beaten you to. Me I would like to see 6.5-06 standardized
 
What about pushing out the 5.56x45mm case to 9mm. Make it completely straight-walled. It'd be an interesting round. Russians did something like that with the 5.45 round.
