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

you must have a lot of coin to shoot that beast.
$42 for the shells and $9 for the bullet so over $50 per pop!
I am out.
 
If that puppy was any bigger, it would need wheels and a crew.

Very interesting collection by the way!

This might be an earlier sporter version.

Here's a video I took of it a while back. I'll take a better one when I am getting closer to firing this beast. I have one surplus cartridge. Unknown if it will fire or not, but I'll try it for sure haha. Will hopefully have some time to get to that within the next 6 weeks at some point over my holidays. The rest of the ammo loading will be a process in itself, I'll likely post that stuff in the reloading forum whenever the hell I source press and dies, likely several months away though. One step at a time with these vintage cannons.


oh my god can you imagine the destruction some one could cause with that!

How is no one speaking out against those 10/22 mags just laying on the floor!

(sarcasm. so chill)
 
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.


Here is a photo (not mine) of some pulled charges from vintage Finnish wartime production ammunition. They salvaged what material they could is my understanding.

Again, this is information from the internet and I don't recommend trusting it without much more research.

And I thought that I was being bada$$ with my 140 grs of 7828 in my 505 gibbs! LOL
 
Found myself a 15 round AA magazine in excellent shape, finish is a bit worn but the metal is in very good condition.

What a monster, the mag alone

It is currently a deactivated magazine with a small weld between the follower and the inside of the feed lips, but I want to reactivate it and internally pin it to 5.

Any ideas on how to properly pin a magazine like this without any external signs or drilling for rivets?

I'll have some photos up shortly.

The magazine alone weighs about 11 lbs unloaded, and is 3" wide, 9" long, and 17" tall. The unique accordion style magazine spring when uncompressed is almost 3' long. The width of this magazine is literally the same as the length of an AR15 magazine.

It is just such a neat piece of engineering history.
