Thought you guys might enjoy this. 20mm Solothurn

[QuietShootr]

In the interest of sharing some of the things I do with those who would enjoy them...Or, what I did last weekend...besides get covered in poison ivy.

First: a round of ammunition with a 1911 for perspective.

In its shipping crate:

Muzzle view:

Chamber:

Magazine well:

With a .300 Win for scale.

Assembled on its carriage:

View downrange:

Right side. Note massive ejection port.

Left side:

Muzzle brake (there are two brakes, this one for firing API, and a single chamber one for firing HE, which is much lighter.)

I'll get some video after I've had some time to edit. Cheers!

'tain't. About $60 a round for original factory rounds. The reloads are a bit less obviously, but they require that you locate 20mm Vulcan projectiles and have them turned down to the proper diameter (it's a little smaller than a US 20mm.) Uses .50BMG primers and a metric fuckton of powder. Ballistics: 4000 grain projectile @2500, for around 55k foot-pounds of ME.

Wow and I thought it was fun to tap off 50bmg ammo when I had one. You may just need to get a CNC lath and just start pumping out your own bullets. Then only to get powder by the shipping container and you will be set.

The "technical" term......

Do you use a measuring cup from the kitchen?

FANTASTIC!

This is very cool, thanks for the great photos. IIRC, these 20s are about 0.008" smaller at the engraving band than 20mm Vulcans.

Can anyone give some more info on the sighting device ?
It looks like some sort of built in optic ?

Not sure, but it looks like it comes with an EREK knob.


Thats an amazing piece of history you have there.

Imagine being some poor guy rolling up on a position in a vehicle and getting caught by an experienced gunner behind one of these. No thank you, I would rather be on foot.

Nice! Can't wait for the video.

Rolling up in a vehicle! Hell imagine walkin in on foot patrol and being surprised by this. You think a .50 does some damage. Better have a DNA record for this one. You can't even take cover behind a BIG tree and be safe from this beast.
