Fireform barrel idea

[Mram10us]

Has anyone taken a piece of rod stock, threaded it to fit an action, drilled a small bore like 22cal then chambered for say a 300wsm to fireform with??

edit- I am already acquainted with hydroforming and normal ff methods. Please stick to the above variables with your ideas.

Sounds like a good idea, but you'd have to consider the 16" barrel length. The ATF would see such a thing as an SBR because it's a short barrel attached to an operable receiver. That you have the two assembled, you have a rifle. Better to take a 16" piece of rod stock and finish it out as you so state. As an American, you have the Right to make a firearm. You could certainly assemble the system you suggest with a 16" barrel, and no one could say sewage solids about it...

An alternate idea would be to have a hydraulic forming die made. I saw a place that does it a week or so ago. I unfortunately failed to bookmark it...

Could a guy do it attached to a bench with a smooth bore? Not sure of the exact definition of firearm but I thought that rifling was somehow involved.

I was thinking a 5" piece of rod stock with a 1/4" drill thru and push in the reamer

As soon as you attach a chambered tube to your action you have a barrel, I use take of barrels or a Wilson, Shaw something along those lines. Also look up making an insert for a shotgun for fire forming, I find this interesting and kinda started on it but lost interest.

The only time I have seen firing forming done by using a different bore was when one of the competitors in pistol matches I shot with used a 7 TCU barrel in a contender and shot 223 Rem in it to fire form the case to 7 TCU. He swore it did a good job but I'm Sure that It was not good for the barrel. I wouldn't recommend anything but the proper barrel and chamber.

There are many safe ways to fire form a case and this would not be one in my opinion.

I doubt a barrel not having rifling would excuse the possibility of having an SBR. The ATF is out there, looking for any and every illegal firearm they can find. A barrel than can fit a cartridge and such barrel being attached to an operable receiver makes the assembly a firearm. If the muzzle is less than sixteen inches from the bolt face, it's an NFA firearm. I doubt ATF is going to accept the argument that the chamber is .30-caliber while the bore is .22-caliber-- or even .17-caliber. The best you can do is to argue that in Court with your lawyer, who is charging you $300 per hour.

The hydraulic forming die is less than $200. Lawyers charge in full-hour increments. The HFD already has you money ahead...

If you do it, Treat it like a 14.5" Ar15 barrel on a carbine, where you are required to PERMANENTLY attache a muzzle brake to bring it to 16"....... if you use a 5" stub, weld a tube to extend it to a 16" length, and make yourself covered from the ATF. Franklin Armory has found a Loop hole with their Reformation Firearm, but I don't think you are covered under that loophole. I too have looked at the shotgun insert, but could never find a Smith willing to make one.....Might be a good learning project when I get my lathe set up.

I appreciate the legalities, etc but I'm looking for experimental brainstorming here. We can assume this is all for posterity sake and continue with the hows and whys it could work

Well if you have looked in the news lately...atf is losing some battles about the lower receiver of an AR being listed as a gun....amd some previous cases are being reopened because they were arguably denied rights to have in possession a lower that was just a lower...
Not a gun....and not the 80% pieces either.....
Kind of the same thing with bolt action receivers.....when has the receiver been able to fire a cartridge without other components attached....

How could they get you for piecing together components to firestorm brass.....kind of ridiculous.....

Are you talking about firing with COW here?

Are you talking about firing with COW here?

Or just a patch if the bore is small enough to get the pressure up where we need it

 

[birdiemc]

I'm no metallurgist or physicist so cant speak to the specifics about the soundness of the idea from that standpoint, but I wouldn't have any reservations about proceeding with the idea, all legality aside....just find an old bugle and solder it on the end you'll be legal and look like Elmer fudd
