50 bmg question

[Rockit]

What is the commercial ammo availability of DTC? I have a RAW that I have been looking into a 50 BMG upper for, but if I can readily get DTC at a similar $ I would just build a dedicated lower.

Those numbers are from Wikipedia.

I believe that Eric design the cartridge to have the identical case capacity as a 50BMG.

There are a few Vendors on this forum who are 06 or 07 FFLs and manufacture DTC ammo for retail sales. But, no matter if you have a DTC or BMG chambered gun, reloading and tayloring the round to your exact gun is the only way to maximize it's performance and precision. The cost of commercially produced DTC is normally within a few cents of BMG ammo.

Is a smoothbore 50bmg legal?

It can't really be a "centerfire rifle" if it has no rifling right?

Luckily, California legislators didn't know about .50 DTC when they created the ban.

fortunately, lawmakers are idiots for having such a narrow mindset...

I saw a post on here about a 308 round being fired from a 30-06 rifle, so I think it is entirely possible for a 50 bmg to be fired from a 50R.


I'm not really looking for a long range 50, I just ponder things a lot. How this particular train of thought came about was, I was wondering if "chambering" rifles above 50 bmg (not in terms of bullet diameter, but in terms of case size, power, etc) was legal in CA. My thoughts are it was silly to enact a ban on only 50 BMG if there are more powerful 50 chambering available, so maybe CA's lawmakers actually thought something through. but I guess They are dumber than they look (very hard in their case) and CA's laws don't make sense anyways so.... yeah

You CAN go to a larger diameter bullet here... (CA DD limit is .60cal)
SSK has a fed exemption for this cartridge:

Perhaps if one could figure out a way to hold the round near the bolt face, but with the shoulder of the .50 BMG round all the way into the 12.7 chamber, the primer will be more than a quarter inch away from the bolt face...

Isn't the base diameter of the 30-06 and the .308 the same? If it were it might hold the .308 round in place in the 30-06 chamber well enough to fire it. The 12.7 base is larger than the .50 BMG base, so the .50 will drop far into the chamber before stopping.

A .22 with a 12 round magazine has more destructive power than a .50 Beowulf AR-15 with a 10 round mag.

Makes sense.

To actually answer the OP's question, yes, you could totally make a bigger/meaner/more powerful cartridge than .50bmg and as long as the rifle for that cartridge is physically incapable of firing a .50bmg cartridge, it would be legal. It would be legal ASSUMING you met all other federal and/or state law requirements. For example, if the rifle has a bore larger than .50cal, it's generally considered a DD.

However, CA doesn't consider a rifle a DD until it hits .60cal. So you COULD legally make a Federal DD, and get the tax stamp for something at or under .60cal without having to jump through any CA hurdles.

You could also take something like a 20 or 30mm shell and neck it down to accept a .50bmg bullet. It sure would be one hell of a barrel-burner, but as long as it was no larger than .50cal and could not chamber and fire a .50bmg cartridge, it would be legal in CA (and federally).

I believe a few people have already built rifles based on necked-down 20mm cartridges, since brass for that is pretty available.

I believe the CA definition of a rifle doesn't require it to have rifling. If it's got a buttstock and can fire .50bmg, you shouldn't have it in CA.

12020(c)(20) As used in this section, a "rifle" means a weapon designed or redesigned, made or remade, and intended to be fired from the shoulder and designed or redesigned and made or remade to use the energy of the explosive in a fixed cartridge to fire only a single projectile through a rifled bore for each single pull of the trigger.

That is a thing of beauty. Must burn through barrels like crazy though. At $7500 I really hope it comes with a set of dies. And brass. Heh.

Wow. For once CA gets it right.

So I guess a smoothbore .50BMG rifle WOULD be legal in CA.

Now imagine one with quick-change barrels. You have a smoothbore barrel for practice/plinking inside CA and a rifled one for shooting outside CA

I need to find some fin-stabilized discarding sabot .50BMG rounds

how about using something like this?

I would imagine that a smooth bore .50 BMG would be about as accurate as a BB gun at 100 yards. Kind of pointless IMO.

Flechettes are illegal in California, unfortunately.

12020. (a) Any person in this state who does any of the following is punishable by imprisonment in a county jail not exceeding one year or in the state prison:
(1) Manufactures or causes to be manufactured, imports into the state, keeps for sale, or offers or exposes for sale, or who gives, lends, or possesses any ... any ammunition which contains or consists of any flechette dart,

(c)(6) As used in this section, a "flechette dart" means a dart, capable of being fired from a firearm, that measures approximately one inch in length, with tail fins that take up approximately five-sixteenths of an inch of the body.



the trick would be to come up with a round that did not fit the definition of a a flechette as CA defines it.
