Wildcatters drive me nuts. YOU obviously know little about firearms, and even less about lever action rifles. The only lever action rifle (LAR) that cartridge will cycle through is one of the modern Rossi Model 92 clones with the bolt safety (the bolt safety actually holds the cartridge square to the breech mortise - allowing flawless feeding). Another obvious problem is primers; I don't think a small pistol primer would be enough to ignite slow burning powder in a small case void with a bullet base that large without creating a vacuum. And super slow powder is all that can conceivably be used in this cartridge; if you don't, the bullet will simply sit there and never move, especially with the weak crimp shown in the picture. Perhaps using a bullet with less meplat would actually allow the powder to burn a little slower and gain an extra 100 fps or so. Anyway, why in the world would you create such a thing when the same could be accomplished with 38-55? You've got me scratching my head...
All I can say is "HA!" I know lots about everything. And I use Bullseye. 3 grains. Even tho it is very tedious, I use a tweezers and a magnifying glass and count out each grain. They are about this big -> . I put 3 of them little boogers in it. So there!

Come on Reverend Jim, there's no need to get nasty and call the guy an ... wait a minute... oops, never mind...

Back in the 1800's we had more or less straight walled cases. Then came the turn of the century where we started using bottle neck cases. It's been 100 years now and the gun industry is waiting for the next big break-through and here it is! ...... the Hyper-Magnum Vat-Necked line of cartridges. What a break-through! This will have the ultra-mag people ditching their guns in droves to stay on the Cutting Edge of cartridge development. The chambering of these cartridges will be interesting. The chamber will have to be in two parts ..... the front part for the Vat-Neck, and the smaller rear part will have to be inside the bolt, which itself will probably have to be recessed well into the breech to contain the pressure.
JimT, I imagine your phone will be ringing off the hook with gun writers wanting to write up the new 21st century cartridge.

Bullseye is a tad faster than I'd use, but if you can get 3 grains in there, well, maybe you know more than I think. There's a stink pig shivering at the rim of the canyon, in a far away place called Oracle, just knowing you're once again in "engineering" mode.
How many expander plugs did you go through to open up that case? There isn't a big crack on the other side, is there? Have fun JimT.

I can see Wiley Clapp sorting through article boiler plate right now in anticipation of his big review of the new "Hyper-Magnum Vat-Necked" cartridge.
It loks lke both Jim & Idiot are trying to put one over on us. That's not a Wildcat at all.
A well versed rsearcher in tis area (well, he's actually in upstate NY) has this to report:
I hate to anal about this, but if you'll look carefully you'll realize that is .471 Finklestein-Hoffmiester Midget Magnum, version 11. Seymour Finklestein and Lars Hoffmeister were of course associated with now defunct Lichtenstein Government Experimental Arsenal at Klwgstunghn, just outside of Sxghtyyngradd. In 1932 they were involved in the development of the Albright- Shyster machine gun, famous for it's ease of cleaning since the entire weapon was made from chrome and sponge rubber. A photo of the machine gun can be found on page 972 of "Famous Machine Guns of Lichtenstein Volume 2" written by Sir Hopewell Biddignton Smyth, HMCS, DDRG, FTHU, KMNG, SSEWNMP, who as we all know is the final authority in this area.
The .471 F-HMM unfortunately was a mere flash in the pan, although rumors of various Super Grade Winchester Model 70's factory chambered in this cartridge still surface occasionally. The most commom cause listed for the cartridges early demise appears to surround not the case shape or the Albright-Shyster MG, but rather the powder used in the military loadings. Produced at the Trygnastintang powder factory near Splighnbbtymk in Eastern Klyggncpop prior to that City-States inclusion into Mignomistan in 1935, the powder was produced from a proprietary mixture of beet pulp, hoof trimmings, whey, bat urine, naval lint and the inner bark of a local shrub found only in that region called Rtyngh, later determined to be distantly related to poision ivy. The burn rate of this novel powder enabled the .471 H-FMM to propel the 371 gr projectile at nearly 6,389 fps while giving an average chamber pressure of only 11 psi. Unfortunately the supply of Rtyngh (pronouced "klgnmmth") was extremely limited and the shrub is near extinction today. No other powder was found to be suitable for this ground breaking cartridge and it died an early death becoming obsolete by 1937.
Cartridge collectors pay premium prices for any example of the .471 H-FMM these days. A recent auction for an unopened box of original cartridges produced by the Government Arsenal fetched nearly $19.00 on Gun Broker.
Further information on the fascinating developments of Finklestein and Hoffmeister can be found at http://www.yagottaloveSeymourandLars.Lchn.org , the site of the F-H Collectors Association.

We addressed that.
Rebated bolt face, telescoping breech.
Extraction is easy enough, but the problem is with ejectile dysfunction.
Don't you sell pills for that?
