Made a new clip only to discover that one of my cameras was not filming.... so no video evidence but here is the situation and the conclusions:
I lengthened my sling from 37 to 50cm be able to hit the target at 30m more easily.
At 10m results stayed the same as far as accuracy.
At 20m I struggled to reach the target but after 30 practice throws got the same results as the shorter sling.
At 30m I had the same problems reaching the target with the 50cm sling as I did with the 37 :(  Only way to reach the target was to aim higher then the actual target.  If I were going for distance I can understand that but I thought 30m should be a distance you can just aim for; or am I wrong?

Am I missing something for 30m distance?  My ammo is only 30g should I try something heavier?

Und noch etwas ist zu beachten. Die Stellung Ihres Rotor verändert sich

I wouldnt use a sling shorter than 60 cms. My preferred ammo is between 120-150 grams.

Try upgrading your gear to coincide with your upgraded distance.

You need to aim much higher to hit at 30m. I am not surprised that 30g ammo has a hard time reaching the target. My 143g lacrosse balls trajectory is much lower when I throw, so 30g must really drop off quick (wind resistance). I would follow Jauke's suggestion. Rusty balls are really nice. They can take some punishment. I can sling them as hard as I can and they don't break (yet).  But you can sling them soft too and they won't go far, as long as there is some sort of backstop.

    50 cm is still a pretty short sling IMO.  My ideal sling length is half my height or 38 inches... 96.52 cm.  I suggest you try a longer sling.

I agree with this, 50 cm is pretty short (this is folded right?) My preferred length, if I put my arms at my sides and hold the sling normally, it is a few inches above the ground. For me that is 27" (~70 cm).

Sie suchen eine optimal Länge im Verhältnis zum Körper? Es ist ganz einfach. Hinstellen, die Arme an der Seite hängen lassen. Die Sling der Hand.
Die Sling sollte bis einem Zentimeter über dem Boden reichen. Das ist eine optimale Personen bezogene sling Länge.  8-)

30 grams is too light for ammo. Try 100 to 125 grams.

Thanks so much for the info.  Going to first make some rusty balls at around 120g-150g,  see how that goes before I change a second variable.  If I still have a problem then I will go for a longer sling. 

I use Greek style release not sure how much that makes a difference.

Hey, ya like everyone said, a little more weight in your ammo will really help it maintain momentum at distance.
I enjoy Greek style a lot. Adding an extra rotation or two might help you harness more power too.
Keep at it! Remember to warm up too

I was doing terribly at the International until I switched to Greek and got MUCH better results. It really does seem like a good style for accuracy but not necessarily for power.

For sling length, my current longest sling is a simple paracord sling that's 142cm centre of pouch to release knot. It's pretty darn huge but actually easy to use with the right technique which I think is true of all slings. A video David put up of Puchi slinging in Mallorca is what finally made long slings usable for me without hurting my arm:

Starting off the sling across the back or across the shoulders gives it that starting momentum that makes it possible to use without having to resort to the very inaccurate pirouette.

For other lengths, it's just practice and getting used to them and then understanding their limitations. If you have a 20cm sling, don't expect to throw across a football field, but that also doesn't mean it's useless. A quick overarm throw at short distances would suit it nicely. Know your sling.

50cm = 19 inches.
yeah that's really short.

My 20 metre sling is (gets it out of pocket and measures it) 22 inches

And with 60-100 gm stones I'd struggle with it at 30 metres - I mean I can throw a rock over 150 metres with it - but for accurcy you don't want to be putting that much effort into the throw.

So yep, heavier ammo and longer sling :-)

Ok just tried 120g and 150g rusty balls.  With the 50cm sling I get the exact same results as I do with the 30g rusty balls. 
Easy to hit 10m
Not bad at 20m
Have to aim high to hit the 30m :(

Then used a 140cm sling using the back release from the video Kick put up in the link.  Super easy to use and on my first attempt going gentle my 150g rusty ball soared over my 30m target coming to rest 60m away.

So my conclusion:  It is all about the length of the sling.  Weight of ammo from 30g to 150g seems to have no affect on distance with a short sling.  (With the longer sling I could not feel the 30g ammo and was not able to fire it properly)

Tomorrow I will cut down that 150cm sling to 70cm and see if that is long enough to hit 30m without having to aim high.

Ich sah vor zwölf Jahren Jaume Darder mit einer sehr kurzen Schleuder 300m schießen. Bis dahin hielt ich das für fast unmöglich.
Das ist möglich, wenn Sie die Physik hinter einem Schuß verstanden haben. Die Stellung Ihres Rotor beeinflusst erheblich Ihre Distanz.
Ist Ihr Rotor nach vorn geneigt, geht Ihr Schuß im Spitzen Winkel nach unten.. Steht Ihr Rotor waagerecht, wird Ihr Schuß ebenfalls nahezu waagerecht fliegen. Möchten Sie sehr weit schießen, Strecken Sie Ihren Arm weit nach hinten. Die Schleuder sollte im Winkel von 45° auslösen.
Je schneller und kraftvoller sich Ihre Hüfte bewegt,desto mehr Power werden Sie haben. Probieren Sie es aus.

Jaegoor, I defiantly will try that. Thank you.  I would like to keep using a short sling if I can. 

Will let you know how it goes tomorrow.

Vielleicht mache ich mal ein video dazu. 😁
Schießen sie nicht site Hand. Mit overhand ist der Winkel besser. Sie nutzen optimal ihr Körpergröße.
Gibt es ein Foto von der schlinge?

This is something NOOC can talk on. He's been using a weighted pouch to sling very light ammo and, from what I've understood, has found it to be quite successful. Throwing very light ammo can often be far harder than very heavy ammo.

I use an 18" Balearic and recently was throwing 200g stones over the 100y mark quite easily. For 30m, I wouldn't use anything longer, as I simply don't find it necessary. It may take a little bit of practice to learn how to harness the power of the short ones though, as if you depend on the arm and shoulder for power you will injure yourself even quicker.

Jaegoor You are a genius!!! I could kiss you right now  ;D 
With my 50cm sling I can now easily reach 30m target and was practicing hitting a tree 40m away.  All my shots where reaching the tree with only 70% energy :) :) :)  2 out of 30 actually hit the tree!

Interesting note! 30g and 150g ammo reached the target with exactly the same amount of energy on my part. 

Ok now that I know how to reach 30m time to go back to working on accuracy as the longest distance that matters to me is 30m. 

Thanks so much everyone  :D

Thanks Kick!  Here’s my engineer/physicist answer: The sling makes it easier to transfer power from your body to the ammo. Power transfer to light ammo is more difficult, and a longer sling doesn’t actually help much if the pouch is too light because wind resistance eats up all the extra energy you put into the longer sling.   Adding weight to the pouch is a way of “impedance matching” that allows for increased power transfer to the ammo at the cost of overall efficiency, because a lot of the energy stays with the heavy pouch. You put energy into the sling+pouch. Heavier ammo means more energy goes to the bullet overall, so it’s better to increase the weight of the ammo unless you are specifically trying to throw something light on purpose.

As far as my experience with weighted slings...My backyard only allows about 17 yards max, and some of the ammo I’ve been playing with is under 10g.  With a 60g tennis ball the weighted sling feels pretty weak... which simulates a longer distance throw... sort of (I think shakli started that discussion). I haven’t tried light weight ammo at longer distances, but I think the best way to do that would be the compound sling if anyone has time to figure out how to throw with one. The timing is still a huge challenge.
