I believe this is it:
There are a bunch of other pictures that show up when you search for the Eargesplitten Loudenboomer. This is one of them:
I don't know exactly what they are - from the sound of it, most of these are just put together as a curiosity.
hah... looks like they'd be good for blowing something up
I'm not sure if this is on the list yet, but this is an interesting intermediate round. Apparently one of the co-designers of the 6.8SPC designed it specially disregarding AR-15 confines.

Well, I havn't built it yet. Just drawing board and calculator work but if I ever do build a wildcat cartridge, this would probably be it:
To be used in the Glock model 20 with a custom replacement barrel and possibly a full long slide (LS) conversion project. My 357-LNAM (Long Neck Auto Magnum) flanked on either side by competing cartridges. Basically just a 357-Sig. with the neck extended to match the length of 10mm brass. Would work in the 10mm G-20 magazines (and for that matter any other 10mm magazine) a lot better then the 357-Sig. (which is too short and rattles back and forth and messes up the stack alignment) with the additional benefits including much better neck tension combined with better case capacity since the bullet would not protrude into the powder area. The already existing cartridge which could be considered as directly competing with my design is the 9x25-Dillion which has developed a reputation for having even worse neck tension issues then the 357-Sig. and offers only a marginal (approx 6%) powder capacity advantage over my 357-LNAM set-up with the additional benefit that a gun chambered for such a 357-LNAM Wildcat could still chamber and fire the 357-Sig. cartridge with complete safety provided the chamber was cleaned before switching back to 357-LNAM rounds (to prevent neck pinching from heavy fowling of the exposed neck area from firing the shorter necked 357-Sig. cartridge). In either case my 357-LNAM round would have an increase in case capacity of 0.19cc added on to the 1.27cc case capacity of the 357-Sig. which although still not touching the 1.75cc case capacity of the 357-mag and falling in at slightly less then the 1.55cc case capacity of the 9x25-Dillion does offer an improvement towards matching 357-mag ballistic capabilities beyond what the 357-Sig. is capable of while offering a vast improvement in neck tension and thus potentially the consistency and accuracy of the cartridge.
Obviously plenty of potential for cast boolits as well; probably have to stick to designs with a GC though. I don't think PB or BB would work very well since a regular 9x19 can be troublesome for lead boolits without using a GC and this would be an even more intense cartridge.
I load for a round that I created, from cut down and turned WSM brass. I call it the .510 Deming Destroyer. Cases are cut to .9, then expanded with a .510 mandrel, this makes the "neck" swell to bigger than the base, so I turn the whole case OD to the same size. It's kinda like a big 45.
Here's some loaded up
I didn't have a mold for the boolits, and one couldn't be located for light enough boolits in .510 diameter, so I made one. Well more like modified a Lee mold. I turned a piece of O1 drill rod to the dimensions I wanted the boolit to be
Then after some grinding to make a cutting edge, I had a cutter for the mold. I placed the mold blocks in the 4 jaw and the cutter in the tool post ran the cutter into the mold and then backed it out till the diameter was correct, The lathe was run at it's slowest speed
Here are the blocks after cutting
And here are a couple boolits IIRC they're around 335 grains
I've been planing on hollow pointing the mold to lower the weight a bit. My chrono has been on the fritz so I haven't got a reliable velocity reading yet.
It's chambered in a homebuilt bolt action rifle, but someday I'm going to chamber it in some sort of pistol.

Wow- great work Zeb!

Zeb- How did you grind the O1 to get your cutter shape and do you have a pic of your cutter?
That is a great idea. I need to do something similar soon and never thought of turning the complete profile first. I've never made any conventional molds before but your way makes total sense to me.
Now that is a good one, Zeb!
What is the COL, since you are using it in a rifle?
As big as a 45 Win Mag?
I like that! That is what it is all about right there.

I am not absolutely sure but think that the .510" diameter may be illegal as it will be classed by BATF as a destructive device.
I am not taking a stand on either side of the fence just mentioning it. It may be a good idea to check it out before you take it to a public range where some jealous individuals may delight in causing you trouble.
Thanks guys, If you guys are interested I could start a thread on my mold instead of thread jack this one.
Alot of stuff is .510, 50 bmg, 500 linebaugh, 50 alaskan, 50-70 etc. The reason .510 passes muster is the wording of the law, law reads bore diameter, not groove, the test is a rod that's just a bit over 1/2" and if it fits the barrel then DD it is, being that the bore is .500 and groove diameter is .510, it passes muster.

Yes by all means- start a thread. Leave a link for it here Zeb!
Is there an official 'Wildcat Database" some wheres where the wildcats that get famous are listed and seen?
I thought that was wikipedia -- but the wildcat has to be sufficiently famous for the moderators there to not take it down i.e. it has to be glorified in the gun rags, and some of the the moderators may be fanboys of a particular cartridge.
I'm thinking about setting up a website solely for wildcats. Maybe I should make it wikipedia-like where members here can independently contribute to it. I'll post here if/when I have it up, but it may be some time.
