I would like to talk about the abrasion of slings from stones during long-term use in general, and also to show my idea of ​​​​solving this problem.

My first slings were jute woven in the Balearic style and I did not notice a strong effect on them, as for example on slings made of paracord in the place where the bag ends.

At first, I tried a sling made of just one cord, as simple as possible. It works great, but the braiding of the bag knot where the stone flies out began to wear out after about 700-800 throws. Then I attached a couple of metal rings to the knot - so far it seems to work

Then I decided to make a sling with a bag from leather strips and increase the number of rings.
It survived 300-500 throws. Testing continues

In the future, I think I will try rings of a smaller diameter.

Maybe someone has already tried a similar approach or can share their solutions?

Dyneema is a brand name for UHMWPE. 

IMO, I see the knotted slings like the first one as temporary.  Quick and dirty to have something while you make something more robust.
The main issue I see is the knots are a raised area that invite abrasion.  I see two main ways to deal with that: protect or flatten.  Your rings are protecting; a reasonable solution.  Erricrice went the other way with their nearly-knotless.  Jaegoor recommends a mallet, something I've tried on my braided slings and it's kinda the finishing touch now.  I don't know how accepting of being mushed the knots you use are, so YMMV.
A lot of natural fiber slings get treated with beeswax to help with this very issue.

Sarosh has another good point: material sciences have progressed a lot!  There are a lot of modern materials that make good slings: UHMWPE and Kevlar are two examples, but even polypropylene is a good contender.  It might not be as abrasion resistance as the other two, but it makes up for that by being considerably less expensive, so replacing it isn't a heavy lift.

Ramble ramble ramble.  Haven't used rings before.  Mumble mumble.  Didn't even really answer the question.

Yes, I saw your channel and that there are slings from it, but I haven't seen this material in real life yet, so I can't judge whether I'll like it. Although it seems to have a lot of positive qualities. Perhaps in the future this will also become my choice.

Yes, the knots are a simple solution and on the green sling I tried to make sure that they were turned towards the bag with the flatter side. And yes, this is most likely my "transitional option" in order to try how the rings will behave. And then it is worth trying the method of pulling the cord through the cord, how does it do Sarosh and Erricrice did with dyneema.
(p.s. just found out what it's called "brummel lock-splice" https://youtu.be/4WW7Qvg3VjI?si=PeTB2xbqmGIFKtLz)
Thanks in general for the addition on the different options.

In this version, I am not particularly happy with the twisting of the rope and the correction before the throw. I read that with dyneema this moment is less, which also leads to the choice of this material. Oh, and I also saw that from twisting someone (I think Sarosh) made a seam along the sling, making it flat.

Ha, thank you!

The rings do look pretty badass, nice!

Thanks for the explanation in the other thread about bending the rings open then shut again after threading them through. Makes sense and would be fairly easy.

But yes, after a lot of testing with dyneema(yet another thread on that coming soon), I would agree it is superior in paracord in every way for slinging. Not just for durability, but also for lack of a separate internal cord(internal twisting is a pain), its increased stiffness given the same diameter, significantly decreased weight for the same diameter, and ability to be rolled flat for better grip and faster reloads!

Still, even dyneema eventually will start to wear if you through rough stones, so maybe we could consider some of this chain mail on the release cord side! Not to mention it is just cool to be able to say your sling has chain mail 

I'm glad that many people liked the look of the sling with rings!

And so, a small continuation of the tests.

Soon the braid on the purple sling (4 mm paracord) frayed above the bag about an inch.

Then I started trying 6 mm paracord. Unfortunately, the store only had remnants of pink
I made it similar to the green one - I put rings on the knot and after it about 10 cm rings (see photo).
After about 3-4 thousand throws of various river stones in shape and size, the sling began to wear out between the rings and I made the rings more frequent and closer to each other.

This protects the sling and knot perfectly, but after another 500-1000 throws, the abrasions on the bag itself became more noticeable

Next, a 4 mm dyneema rope is waiting for testing.

And the shape of the sling, by the way, I really liked it both in its simplicity of manufacture and in the ability to throw stones from about 2 to 8-10 cm in diameter. For throwing the ball, I made the same shape, only the bag is slightly larger.
For throws for accuracy up to 20-30 m, I use a release from above using the figure-eight style, for throws at a distance, I spin it over my head and a little behind me with a horizontal release.
