20 mm Load Data

[JRS]

6'-8" long, with a 5000 yard range. OOOWEE 8)

That's 4' longer than I am in height ;D

My fondest memory of the 20mm cartridge was it's home in the Vulcan gun. You have never heard a sound quite like a Vulcan gun in an early (C47) version of Puff the Magic Dragon raining destruction on the goobers trying to sink your freighter as you work up the Long Tau river from Vung Tao to Nha Be. That sucker could chew up real estate at an unbelievable rate...

Timing was everything - we had a problem and he had half a load of ammo he really didn't want to take back to his airbase; 37 seconds after our problem began he came over the horizon and took care of it. Spectacularly.

The idea of handloading that round never occurred to me. ;D

I will admit I saw these on the Anzio website and was instantly wanting one. All I could think about is how awesome it would be to shoot a hog with one and see what happens.. BUT I cant even find a need for a 50BMG, and I try to find an excuse at least once a week... HOWEVER I am somewhat recoil sensitive, and my max is my 338 Lapua that I built to not have bad recoil... I don't think this would ever be of value to me haha.


But seriously, if you ever shoot an animal with it, call me sick and twisted, I'm fine with that, but I want PICTURES!

Ah yes! The 20MM used in M61 Vulcan gatling gun in the formidable F-14! What a sound!

The NFA requires that certain “firearms” be registered
and imposes taxes on their making and transfer. The term “firearm” is defined in section 5845 to include “destructive devices.” The term “destructive device” is defined in section 5845(f)(2) as follows:

[T]he term ‘destructive device’ means . . . (2) any type of weapon by
whatever name known which will, or which may be readily converted to,
expel a projectile by the action of an explosive or other propellant, the barrel
or barrels of which have a bore of more than one-half inch in diameter,
except a shotgun or shotgun shell which the Secretary finds is generally
recognized as particularly suitable for sporting purposes; . .

We referred to the sound as an elephant farting. The early (first) C-47 conversions were called FC-47....fighter drivers objected and it was changed to AC-47. 1st one had 50 caliber BMG's mounted (Terry and the Pirates).(Done at Hulburt Field FL.) "SPOOKY" is the call sign. A variety of weapons were tried,(7.62-20mm Vulcan all firing through the rear two ports (windows) and rear door on the port side.) In my opinion all were successful, just some better than others.
It was a relatively short lived system as AC-130 "SPECTRE" started replacing them. The AC-130 (still used today and allegedly stationed in Hulburt Field.) SPECTRE was armed beyond imagination from 7.62's to 105mm Howitzer with variety between the two.
Yes, we could chew up real estate at an alarming rate in that AC-47 and the AC-130 did it ten times better (and longer).
The above is from my memory a long time ago (so there may be an error). One thing that is clear is from the radio chatter there were quite a few army and marine personnel that were happy to see us arrive on station.
The last American AC-47's were transferred to the VNAF and me and those SPOOKY's left about the same time.

You would have no idea how much it pleases me to read your comment.

Yes they are still at Hurlburt Field and our sister flight the 193rd Special Operations Wing (electronic warfare) here in "Pennsyltucky" took care of the PSYOPS for the ones that get away.

And the gun ships are "VERY" accurate shooters!

If you go on you tube I believe there are a few guys shooting the 20mm and about a mid teens girl shooting one.

Mike at Anzio will have all the info you need to load with and he is a real nice guy. H870 is hard to find but WC872 not so much, US869 would probably work also.

Appears to still have some pulldown WC870 in stock, plus WC872.

I wish I had a dollar for every 20 mm. round I loaded into A-4s. I would custom belt ammo if pilots requested it.
