Gotta feed the beast... Finnish capgun...

I'm getting different info from various people, and from various different firearms, so I don't have a load I consider correct yet, but the average load seems to be a duplex load.

10gr black powder in a tea bag above the primer, followed by a 550gr-620gr load rolled in silk or similar material cylinder to take up volume.

550gr charge with 1550gr 20mm vulcan inert training projectile apparently net approx. 2700fps, while a 620gr charge with the same projectile will hit 3000+fps. Should be getting up towards the 30,000 ft-lb - 35,000 ft-lb range...

So it is a marginal cartridge for whitetails, then? LOL
 
Kevin,
Why SS for the cases? obviously it's what the seller is offering, but was there any insight givin on selecting SS over brass?

What life would you anticipate out of the steel cases? 2-3 loads?

The reason as I understand it is that for cases of this size, sourcing the correct brass is quite difficult and expensive as it has to be a fairly specific type of brass.

I was told to expect a case life of 2-4 loads, depending heavily on variables like how much the brass expands during firing/ resizing, and how hot they are loaded.
 
IMG_20170127_183704.jpgMy two mags are a little different than yours, the difference being the side rounds windos. Mine look to be larger 1/2 with a clear film covering the holes. Both of the magazines feed lip have been hacked off, missing one follower , one has a cross pin welded between the shoulder and the one with the follower the spring is broken off and is missing. I do have the carrying box for them with leather sling . I have one complete round brass with steel projectile and one empty case ( copper) un fired . The smaller mag is for a20x110 hispano AA cannon. 8 round welded follower and locking lug removed.

Nice guns! If you need help shooting any of them (but especially the Lahti) let me know :). I live close to you but I'm wondering: where is the nearest range to Edmonton that allows .50 BMG and up? Both CHAS and SPFGA do not...no hard feelings against them because they are just not set up for it. I would also suggest making a 20mm bullet mold and produce some cast lead powder-coated practice rounds. Or I could turn some brass projectiles on my lathe. Hmmm...this seems like a fun thing. If you don't mind me asking; what is the going price for those Lahtis right now?
