Hello,

upon special request, I have looked into ways how to shoot shot pellets with a slingshot. Using the conventional leather pouch does not work, as the pellets fly in crazy directions. Therefore I made a pouch that has been formed from thin Kydex (a plastic that you can form by heating it).

The new pouch holds up to 50 .177 (4.5mm) lead or steel pellets. Since it does not open fully, the groups are fairly tight, which is shown in the video.

This includes slow motion scenes recorded in Hi Speed (1200 frames per second). Watch how the pellets smash through beer cans! Spectacular scenes.

This won't kill a Zed, but probably undead snakes and rats.

The slingshot used for these tests is the Cougar, the first commercially mass produced Jörg Sprave design. It is demonstrated in detail in another video (currently awaiting the approval of the Dankung company). You can order your Cougar at www.dankung.com!

Here is the video:

That is great, I wonder how well it would work with random small rocks and such that could be scavenged? That would definitely take care of pesky animals around camp. Extra kudos for the video.

That kicks ass. Can you do a post on forming the pouch? The slingshot in the video uses flat bands but the one you linked to show tubular bands. Which type works better with shot?

The pouch can also be attached to tubular bands, either with the "kink and tie" or "knot in tube" method.

I prefer flat bands, they are simply faster at the same draw weight.

Rocks and other small stuff ain't good ammo for this. You need heavy pellets as otherwise the impact is not hard enough for any serious damage. So lead shot works best.

You killed that beers... :(

other than that: Awesome! :mrgreen:

ETA: as for the improvement of the "scattershot" with leather: have you actually tried to sew a piece of leather shut on three sides, leaving only one side open? I feel like that would possibly tighten the pattern, if it opens enough for the shot to go out...

Is it bad that I've watched enough of Jörg's videos, that when I read his posts I hear them in my head with his accent? :lol:

Is beer cheaper than Pepsi there? Man, that's just alcohol abuse! :lol:



OT: I noted your explanation for the glove in the video. How bad is the hand-slap from one of those things?

That's awesome. Just out of curiosity do you think it keeps a tight enough group to bust clay pigeons?

That's what I was worried about, thanks. Probably can't find a lot of lead shot lying around unless there are a bunch of people around shooting at the same spot. :wink:

You can reuse air gun pellets, just visit a range and you can harvest the stuff for free.

Depends on the beer i´d say. But beer cans are usually bigger than soda cans... 0.5litre for beer and 0.33litre for soda

Us weak europeans are not used to soda, you know. Therefore we gotta be carefull with that stuff and it comes in smaller packages. Beer on the other hand..... we can cope with beer :mrgreen:


ETA: woohooo! look at that: my post count say´s 357 :D

In fact it is pretty hard to find any kind of beverage in cans. The German government decided to make deposits for beverage cans mandatory, so plastic and glass bottles are now cheaper than cans.

I had a hard time finding beer cans - but they make such nice targets, especially when you shake them well and let them sit in the sun afterwards. So it was worth it.

It is awesome you are bringing one of your sling shots to market. I will have to buy one, once my economic situation improves.

I am always impressed with not only your concepts, but the execution of your ideas.

That is somethings I have been thinking about for years and never would have thought of using Kydex for the shot "pouch". Perfect!

Again, great job and a very well done video!

I have done some slomos to see how the pellets leave the pouch.

Interesting, the Kydex pouch flies high after the fork has been passed, while the shot pellets continue straight on.

The pellets are in a nice tight group, just perfect if you ask me.

Then, the pouch returns downwards. I have no explanation for the strange post-fork flight of the pouch, maybe it is because of the hollow container halfs. Well, I don't care as long as it works.

The pouch design is brilliant. Are you going to try to market that? I'd buy one.

Buy a 25 pound bag of lead shot. :D By the way, awesome slingshot as usual.

Im a little late on this post.

Is this something you would say has a high enough impact for say squirell and rabbit? If so, it could be an excellent survival tool.

I'd be amazed if it couldn't. Squirrels and rabbits don't exactly have the strongest bones out there.

Hmm, 8 gr .177 BB(average pellet weight, going from a quick Google search) x 50 is about 400gr, which is what, 1 ounce?
