Solothurn S18-1000 20 mm

The Treaty of Versailles that ended WWI severely limited Germanys ability to conduct research and development of military hardware. In order to circumvent this the German firm of Rheinmetall acquired a controlling interest in the Swiss firm of Solothurn. Solothurn developed some interesting small arms in the 1920’s and 30’s. The S18-1000 was their premium Ant-Tank rifle, semi automatic firing the 20 x 138B round. Commercial sales were disappointing and as an anti tank rifle she was obsolete before WWII started. These rifles did see limited use, mainly in North Africa. Many were sold as surplus into the US in the sixties for $189.50!

She weights approx 120 lbs and is over 7 feet long. The cocking handle is a crank, two and a half turns are required to pull the breech block to the rear, the breech block is held to the rear by the sear and the crank reversed two and a half turns. When a loaded mag is inserted the breech block “thunders” forward and chambers a rd. She is equipped with a telescopic sight, the body of which is machined as part of the receiver and has back up iron sights.

HELP PLEASE - I am looking for loaded ammo, empty cases, operators manual, original transit box, spare mags and muzzle brakes. I believe a few years ago Sarco listed spare mags as “door stops” any one care to part with one?

Both the Italians and the Swiss had a wheeled mount for this girl, one of them would make a good conversation piece.

I remember there being some reloading info but its hard to do. Good luck, I'd love to see what that thing would do to an elephant!
 
Collectors source has some 20mm cases listed, as well as a Solothurn practice round ($85).

The empty cases are Finish, and I would assume for the Lahti. The Solothurn round is belted, where the Lahti round does not appear to be.

Edited to add: Wikopedia lists the 20mmX138mmB round as also applicable to the Lahti M39 and M40. The B in the designation is for belted...not sure what the 20mm cases that collectors source is showing are for as I do not see a belt. But the practice round is likely correct. Adapt a 50 primer, and turn solid brass bullet. The adrenaline rush will be worth the $85.
 
Mr. Wolverine, did you reload these cases yourself, or were they loaded cartridges?

I have an Lahti L-39 on order, and have ordered 50 CNC turned cases (made to accept .50BMG primers) with 400 CNC turned projectiles, but am still looking for modern reloading data.

If anybody can point me the right way, I would be very appreciative.

Kevin.
 
My buddy Craig reloads for me, I just get to pay all the invoices. Send a PM to "Missing something" and Craig can fill you in on the details, we are getting some projectiles manufactured as well.
