.50BMG necked-down wildcats

[SpeedAKL]

Nope, I haven't shot most of the cartridges in that lineup, it is really just a cartridge collection. The .375H&H is the only one I actually own a rifle for. Whilst I love magnums, I don't know that I would want to shoot the 4Bore with a 2000gr. bullet pushed out by 450gr. of smokeless. OTOH the wee little 12Ga.FH should be similar to the .700NE, so still quite a decent shove. I'd give it a try, but don't know that I would be asking to go two rounds with that heavyweight.

Nice, I'd love to hear the sound of that 4-bore being touched off!

There is something appealing about unnecessarily powerful rifles IMO. Nobody needs a .700NE even for African elephant, just like no one needs a Bugatti Veyron, but it's sure cool that such a thing exists! The biggest gun I've touched off are 12-gauge magnum loads. Some of those produce roughly 60 ft-lbs of recoil and that was painful...while a .600NE is roughly 140 ft-lbs! Insane...

I remember seeing a picture of a .50BMG-chambered rifle designed to be the same size as a typical dangerous game gun. It used a strandard size stock, the only way to tell it was the hugely thick barrel and muzzle brake. It weighed 14 lbs IIRC. Apparently recoil was violent and the muzzle blast was bad enough to shatter nearby camera lenses.

You and me both. The round is comical in scale, most folks I show it to don't believe it is a genuine rifle cartridge, and at over 1in. in diameter I can see why. At about 0.5lb it makes one heck of a paper weight. Being a live round, I am just afraid it might roll off and hit the primer...which would be like a pipe bomb going off.

Its been done... I have also seen a picture of a sabot inside of a sabot in a 50 case making it a 22-50 I guess.

Wow, that looks....amusing

I can only imagine what the chamber pressure would be, trying to squeeze it all down to that tiny hole. I wouldn't wanna be on the same range that day.

I would doubt such a cartridge has ever been fired, though. I have a bunch of oddballs sitting around that I made, like a 10mm auto necked down to 6mm with a 63 gr. hacked-off Sierra FMJ.

I'd like to be the guy selling him his barrels! lol hehehehe

While it isn't a necked-down wildcat, there is the .50 DTC, which is just different enough to give the finger to Ca's stupid ban on 50 BMG.

I have always been interested in the wildcats that require the .50 BMG to be necked up, like the 14.5 JDJ...

+1, it can go a little faster (fastest is around 5800fps IIRC), but that is near the limit for smokeless powder. I don't believe that 6000 Ft/s (the theoretical limit of chemical propellants) is possible, or at least hasn't been achieved.

Top load (velocity) listed @ Reloader's Nest belong's to the .22-243 Middlestead. Chrono'd at 5278 fps. I don't doubt that there may be some faster though...

Here are a few...compared to a .338LM on the end:



This is one I did based on necking UP the .416 back to .510
I call it a .508 with the idea that it's like the 30-06 / .308 relationship:
