The New .50 FUCA Rifle. PRK Legal!

[nvrquit]

Why not ".308" the .50 BMG or has that already been proposed?

I know it wouldn't satisfy the "magnumize or nothing" crowd, but to my mind it would be more efficient, allow the use of the .50 BMG parent case as a base for the new round, give nearly as good performance with the lower projectile weights and beat the PRK as*%oles. The performance of the round should be in the same area as the .50 Peacekeeper(or a bit better) without having to deal with the PITA belted brass.

Additionally, all the current .50 BMG designs should be able to be altered/converted with little trouble(relatively compared to most other alternatives), using almost all currently used components(mags, barrels,etc.).

I know I'd want one, but then I also would like a .50 BMG to start with.

Cute. I was thinking you could make it the ".498 Feinstein" just to make things really interesting. Can you imagine the look on her face when she heard about it?

What about Sabots?

Part of what will make the round illegal in California is that the bullet is 50 caliber. If the 50 BMG brass is left intact, and a saboted whatever (308, 338, etc) is inserted, then the round is no longer a 50 BMG. To prevent a 50 BMG from being fired, the barrel will need to be modified-say .49?-but the sabot itself can compress the 1/100 of an inch. If a sabot jacket is used on a .30-something round, is it conceivable for an aftermarket barrel liner or sleeve to be fitted (which would be much less expensive than a new barrel)?

Please tell me the weaknesses of this idea.

the law doesn't say "can fire a 50 bmg safely" just fire period. Some people have fired 7.62mm bullets down a 6.5mm bore, wasn't safe but it was done. You could fire 510 bullets down a .49 bore, I wouldn't do it, i'm just saying.

Antibubba,

50 BMG pressures are too much for a barrel sleeve. You would need a new barrel. Accuracy with sabots is mediocre and defeats any purpose I'd want a 50 BMG for. It's not impossible. You could do it using a new .500" (instead of .510" of the 50 BMG) barrel blank. This is already in production because of interest in the 50 S&W. It seems a lot of work for no benefit.

Why not just neck the .50 down to .408 and blow the cheytac out the water!
.338-50 talbot has been done but was overbore!
new round would solve chambering issues uses and uses current available parts! still not a fifty though!

An alternative to the .50 already exists, called the .50 DTC. IIRC it's a cartridge of french design, where NO military cartridges are allowed to civvies, such as California.

My understanding of the law is that as long as the rifle does not meet the specifications for .50BMG then it is legal as long as it does not meet the requirements for an assault rifle. I have heard of some talk about making rifles in .512 or just slightly lower caliber, all that would do however is cause the PRK not to allow anything over .50 or perhaps even less.

 

[Shifty]

barret already gave the PRK the bird by refusing to sell or service any California govt agencies and developed the .416 barret round

Once you get above .50 cal, federal laws get very picky as to which gun firing the >.50 is a Destructive Device and which one isn't. I forget why shotgun slugs are exempt, tho...

Shotguns and some firearms over .500" bores are recognized as being "particularly suitable for sporting purposes" and are not NFA regulated as DD's. .600 NE, .700 NE, .585 Nyati, etc.

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, you can use those 50bmg bullets but load them to waaay higher velocities. Even outside of Kali a rifle chambered in this round will be a great seller. I would buy one! Really, what do you all think? It shouldn't be that difficult, 20mm casings already exist, and it wouldn't be regulated as a destructive device because it's 50 caliber.

this one I nominate for ".50 Feinstein" - nothing like having your name associated with the biggest, meanest cannon legal for the man on the street. You know what, it'd be either an honor or a slam as appropriate.

This is the reason I hate hanging out on discussion boards with people who don't live in California anymore. You guys are just making crap up. It is perfectly legal to have military calibers in California. Otherwise we wouldn't have 5.56mm, 7.62mm, 9mm, or .45 ACP in California. Now that is just plain dumb.

Further, specifically the .50 BMG was banned in California. It was banned by exact measurements. So if you shorten the case a little and change the neck angle so a standard .50 BMG will not fire in the rifle, you no longer have a .50 BMG. That is why the .510 DTC is legal in this state. If you go all the way back to the beginning of this thread you will see it is a rather old thread.

Not quite sure why a two year old thread was resurrected, but it needs some correcting.

Just to set the record straight on the terminology in the originating post on this thread. The post stated that ".50 FUCA" is a nonsensical term used just because it sounds neat. .50 FUCA is incorrect. It is a mistype (or intentional misuse) of the originally proposed designation. The correctly spelled phrase - .50 F.U.CA - had a very specific meaning.

I should know - I proposed it.
