The New .50 FUCA Rifle. PRK Legal!

I like the ".50 California Magnum", it rolls off real easy. Speaks to my rebelious nature. And km is kilometer so the anti's will suspect it's made to go about 50 miles or thereabouts. It's an over the horizon weapon.

Somebody better trademark that name, it's catchy. I think I hear a song out there, maybe a poem.

The problem is no one has got back to me on this yet. Only Watson Weapons even bothered to respond. If we are lucky it is because someone is having their lawyers figure out how to make the .50 FUCA wihtout giving us any credit and making all of the money for themselves. Heck, just give me a copy and some ammo and I will be more than happy to sign my product rights away.
 
What about getting a hold of some 9x90 and just necking up to .50BMG?

The length should be under limit, thus preventing a true .50BMG from chambering. You could do this simply by changing the bolt (fo r a bolt action rifle) and chamber.

I don't know how common H&K's 9x90 was though. Was it ever produced?

:D

As to technicalities: the quickest is to shave a couple threads off the back of the barrel, shorten up the OAL. Need new load data brewed up though, unless the shoulder was altered to regain volume.

Probably the most practical response is to swap barrels to 338Lapua.
 
So, there's room out there for more than one california legal 50 alternative. I just like my idea of the 50 KM since it sounds cool whether you spell it out or just say "KM" and since it's based on a 20mm casing it will way outperform the 50 BMG. Sure it will be expensive, but if you build it, they will come. The best part (financially speaking) is that the 50 KM will have excellent sales appeal OUTSIDE of california, since it will be the new KING OF MAGNUMS!

That's right folks, line on up! 50 BMG just not enough for ya?! Always looking for that something more? THEN LOOK NO FURTHER! The new 50 California MAGNUM is here and simply blows away the competition. 26,000 foot-lbs of energy! Accurate to distances greater than 2 MILES! See the amazing truckasaurus fight the 50 KM... uhhh got a little carried away there.

Anyway, I really want to do this, the only problem is the initial production costs. Would anyone want to try putting this together with me? Do you think it would be a good idea to build one working prototype and then sell the design to Armalite/Barrett? Heck, even if Kali outlaws it (which they will eventually) it would be cool to have a law specifically written because of you! And even then costs can still be recouped in free America.
 
blackrazor,

Why not build the 50 KM (California Magnum)? Go bigger... WAY bigger. It's the american way. I suggest necking down a 20mm to .50

Been done. It's called the .50 McMillan "Fat Mac".

The problems with it are several:

1) Obviously you can't load these things with any ol' setup. ;)

2) 20mm brass is almost all electrically-primed. You need to use an adaptor to get a .50 BMG primer to fit the base of the flash tube. (On the upside, it has a flash tube; ignition is consistant and long-range accuracy is supposedly outstanding.)

3) A 750gr bullet at 3,425fps generates just a tad bit of recoil, blast, and boltface thrust. 19,545 ft/lbs of muzzle energy is nothing to sneeze at (that's half again more than a .50 BMG. Or, think of it as a .50 BMG plus a .458 Lott. ;) ) The few rifles in this caliber tend to be monster rifles with 42" tubes, massive custom McBros receivers that dwarf a .50 cal rifle's, weigh a ton, and have prices in the early ionosphere.


If you're going to use 20mm shells as the base, why not go all out and resurrect .950 JDJ? ;) (Also, any .50 BMG rifle could be easily rechambered to .700 JDJ. It's just a .50 BMG case blown out to .70 cal, and bullets, dies, and cases are available from SSK Industries. 1100gr bullet at 2,200fps sound fun? :D )
 
I want one :)


Seriously, is there anywhere I can go on the web to read more? Should I just call McMillan?

P.S. Tamara, wouldn't necked up 50BMG rounds be destructive devices according to the fed?

Nope.

Well, more accurately, "Not necessarily."

The .700 JDJ and .950 JDJ have both been declared by the BATFE to not be DD's.

Pics at the bottom of this page.


Incidentally, according to Cartidges of the World the last list price for loaded .950 JDJ ammo was $30.00....

...per round! :eek:
 
What happened to the idea of keeping it simple and just cutting the neck on a .50 BMG and calling it something else? I do like the idea of creating something bigger and making it appeal to all of America with a "in your face" California name. But lets keep it reasonable.
 
El Rojo,

The problem with cutting the neck on the 50BMG will be that the powers-that-be will probably claim that since that round will chamber and fire in a 50BMG rifle, it is 50 BMG. It's sort of like banning .357 magnum, but claiming 38 spl is still ok... maybe it is, maybe it isn't. Then again, maybe it only works the other way. I don't know... and god knows the people writing these laws don't. Hmmm, this is giving me a headache. ehhhhh, all I know is that I hate the liberal lawmakers here. :barf:
 
Not true Blackrazor. Someone corret me if I am wrong, but if you trim enough of the neck off, the chamber will also be shorter. So if you tried to insert the longer .50 BMG round into the gun, the bolt would not close. I know the brass will still fit in there on some minor variations, but what about a tenth to a quarter inch?
 
If you're having to recut whole new chambers, there's no reason to cling too tightly to the old cartridge dimensions.
 
Tamara,

I have to disagree a bit. I think keeping the case close will provide 2 benefits: Ease of modification to 50 BMG if the rifle is ever sold outside CA or AB50 goes away, and the ability to use off the shelf components and equipment to keep cost down.

I like the short neck version. It can still make use of standard data, can use the same dies, and only requires a slight modification to the reamer. In a repeater you'd have to find a way to crimp, but that is it's only downfall. It seems a reasonable and logical way to avoid the ban.

Tamara,

I disagree a bit.

I think keeping close is a good idea, esp. if one can use standard dies and load data and be able to rechamber to 50 BMG if the need arises. I like the short neck version.

I propose the name 13mm Govenator.

A 20mm necked down to 50 caliber would be legal, wouldn't it?:p
 
Are you insinuating that I don't understand you the first time? Is that why everyone is posting two or three times. Is this a statement about me? :D

I think the most important thing is to make this whole project easy to accomplish and make the switch as cheap as possible. The way you get around the ban is change the name of everything. So what is the cheapest thing to change? Cut the neck down to where a .50 BMG won't fire in the gun and place a new stamp on the base. You would be able to use the same bullets, powder, and primers. The gun is going to have to be changed regardless, but how hard is it to simply shorten up the neck area in the chamber a tad bit and stamp a ".50 FUCA" on the barrel?

The other part about just barely changing enough to make it legal is it makes the .50 FUCA live up to its name. Yeah you tried to ban this, but look, it is back. Where there is a will there is a way. You might even be able to get people outside of the PRK to buy a few too as they will be able to convert the brass no problem since they won't care what is stamped on the brass. You might also be able to fire the .50 FUCA in a .50 BMG, but that is ok as long as you can't fire a .50 BMG in a .50 FUCA.

So what is up manufacturers? When are we going to make this happen? Someone is sitting on a gold mine out there. I might have to find a gun smith and make this happen.
 
but how hard is it to simply shorten up the neck area in the chamber a tad bit

You can't just "shorten up the neck area" in a chamber. You will need to design a new chamber reamer and ream a new barrel. (Not sure I'd want to play the "set back and re-cut" game with .50 BMG...) Of course, once the reamer is made, you can ream as many barrels as you like. If you are having to cut new chambers in .50 barrel blanks, like I said, why not go a little crazy? .50 PPC or something? This project is not going to be "cheap" no matter how you look at it (nothing having to do with .50 ever is,) so why not make it cool? Economies of scale would make even the .700 JDJ cheap, if you Californians are as big an economic force in the shooting world as y'all keep saying you are. ;)
 
its been done

i cant rember the web page but they do work on T/C's . It's called the 50 peacekeeper or is it peace keeper
 
here it is

SSK is now making new sporting and tactical rifles from Brown and other new actions such as Sako. A wide variety of actions, stocks and calibers are available. .50 Peacekeeper = 88% of a 50 browning from a 23" barrel plus brake in a 13-14 pound rifle. Recoil is not as bad as most 35 pound 50 BMG rifles. It does 2400 FPS with a 650 and 2200+ with a 750 hornady with excellent accuracy. http://search.netscape.com/ns/boomf...st=1&remove_url=http://www.sskindustries.com/
 
ya but that cartridge is essentially a straightwalled cartridge. I want a short and fat bottle necked cartridge ala PPC case design.
