Who can make a 20mm barrel blank

nanewt02 · March 13, 2013, 09:36 PM

Anyone know of anyone who can make a 20 mm rifled barrel blank. Pacnor has one but its not actually 20mm. Person or company? Or even a worn out Vulcan barrel

20mm is the same as 10 gauge (10 bore) so such a barrel is not that hard to find.
What type of gun are you going to be working on?
Muzzleloading or breach loading?
Is it to fire a bullet or a ball?

Ed Rayl can do that kind of work, as can Oregon Barrel I believe.

I would consult Lilja about their capabilities.

They provide deep hole drilling services for more industries than standard gun barrels. Probably have the tools for the job to make you a 20mm barrel blank. I would call them knowing the twist rate you want and how much you are willing to shell out for the project.

I think your best bet is to call up various major barrel manufacturers and figure out which ones are capable of doing the project within your budget.

10 ga is a no go . bullet size must be 20 mm for it to work right. So groove to groove diameter needs to be 20mm

Actually I was wrong. 20MM is about 20 gauge.
.625" 20 gauge is .620"

No 20mm is the same As .787 I think

Rifled 20 mm is a destructive device, might need a NFA tax stamp if you're in the US.

It's for a muzzleloader so it's fine

Lynnwood guns had a number of 20mm barrels and bullets.
He has cancer and is shutting down. I don't know where all the hardware is going.

Nenewt, 20MM is .787"
I gave up on my math skills and ability to convert, and just went to my shop and measured it.
So a 20mm is a slightly loose 10 gauge. The "standard" for a 10 bore is .780

There is a outfit in AZ called AZ Iron Works or something.
They make sniper rifles on steroids.

20mm or something. From what I know the FBI's elite HRT(hostage rescue team) made a stink about 5/6 years ago by contracting the firm for a few 20mm sniper rifles.
I think they do custom work too but you'd need to track them down.
