I'm Jealous. There are some fine wildcats there, must get to work and make one. The only wildcat I got was this one.

I think that this one qualifies. .270 Max - a .357 Maximun necked down to .270. A factory RPM XL single shot pistol chambered for this cartridge. No one that I have found shows any data for it. I have loaded it with powders 2400 to H335. Averages about an inch and a quarter off the bench at 50 yards. Recoil similar to a 357 Mag.

I only have a 300/221 Fireball - a takeoff on the 300 whisper. I have had several orphans (no or tough to get factory ammo) like the 41 Colt - but If I was to make a wildcat now it would problably be taking something like the 458 socom or 50 hushpuppy on. I think that my tastes have changed to something that I can shoot quietly and preferable with cast bullets.
I made a 30-357max long neck. Has a 30-30 length neck on it. Have a MOA pistol chambered for it that I used to shoot in IHMSA.
Also made an xp-100 chambered in a 44-284win that I shot a few times in IHMSA. Lots of complaints of the noise (65gr h-335 IIRC w/240 IMI bullet). Chambered a rifle in it too. Took an Elk with it. 265gr Hornady @2550fps.
Think I might have a reamer made for a 44-350Rem mag. Or maybe a 375/350 or 411/350. Haven't decided yet.
Will get pics of the two if I can find what I did with the ammo I still have loaded.
the 338 Spectre is actually a 10mm Magnum necked down.

The 223 blown out is called a 338-223 Straight.

BWE is also making one:

Here's what I was talking about in modifying the 223 Rem. to have a longer 222 Rem. neck to support the 6mm boolit (245498).
I ran a 223 case into a 222 Rem. trim die to form it, then up sized the neck in a 6mm Rem (244 Rem) sizer, then seated the boolit with the 6mm seater die. Of course, proper dies would have to be made if I get serious about the wildcat.
This is just preliminary review, to see how it looks, etc. The gas check on the boolit is seated to right where the neck ends, and shoulder begins.
Left to right- 5.7mm Johnson (22 in a 30 Carbine case), 221 Fireball empty, 222 Rem empty, 223 modified/6mm wildcat, 223 empty. Might call mine the 6mm Longneck.

That looks like a good one to me Charlie Sometimes, thats the biggest problem with a lot of these cartridges neck to dang short for boolits. Gotta love them long necks.
Charlie that looks great. I know the 6x45 is real popular in South Africa, and I guess you *could* call what you've got the 6x45 long-neck. But only if you wanted to...

They are all awesome. I gotta journey into he wildcat world someday.
MAYBE even the 6x45 CB (6x45 Cast Boolit)!

A while back I bought a 22-30-30 reamer from a member here.. Last week I started making a new monobloc for my TCR-87 and will need to aquire a 22 cal barrel to chamber this cartridge. Dies for it are available from RCBS but are expensive at $140.00 or there abouts. No pictures yet as I don't have those dies.

How do you like your 35/30-30? Seems like the 35/30-30 in an 1894 would epitomize an ideal brush gun.
Any cases issues? I'm very tempted to pursue a .30x.223 build (I believe it was first called .30 Apache), but I heard neck splitting when using .223 brass in the 7mm TCU was a serious issue. Any issues for you at 6.8mm?
That's one very interesting cartridge, particularly for boolits. What bullet weight are you using and what fps are you getting?
Seems we have the same goal, though I'd like something quicker. Concerning the .30 Carbine, the Remington .30Carbine JSP apparently yields very nice terminal damage at 2k fps (source link -- good read in general by th way). I personally don't put a lot of stock in yaw/fragmentation. The JSP in a .223 case is quicker by several hundred fps, in fact almost approaching .30-30 performance.
There was a project recently called the 7.62x40. The developer has not responded to a PM I sent him. Looking over his AR15.com thread, I think he just got too beat up and fed up with the SPC/Grendel fanboys and just doesn't want to talk about the cartridge now. The trade off with the .30 Apache/.30 TCU/.30x.223/7.62x39USA/7.62x40 is that there's not a lot of room to play with for bigger boolits. The .30 Whisper fixes this issue, but to the detriment of case capacity. I'd like to get .30-30 performance from the .223 case, which is just about doable with only the lighter .30 boolits/j-words.
I'd love to start with the .30 Apache idea, and trade just a little case capacity for a bit longer neck to accommodate a bit longer/heavier boolits. I'm going to have to crunch some numbers, but a case dimension starting with .223 dimensions but modified with a neck to accommodate up to a 135gr (.30) boolit sounds ideal.
That 6mm longneck is precisely the sort of animal I'm interested in, albeit at .30cal. Thanks for the inspiration!
Yeah, it's 10mm based. A while back I had the privilege to chat with Marty a bit via email concerning the .338 Spectre and the .458 Socom. I posted the correspondence somewhere, but I can't seem to find it. I think it's on AR15.com somewhere, hidden from search engines. I'll try to remember my rarely ever used login there and post the correspondence here.
