Here is an easy sling to make. The pouch holds the ammunition securely without any interweaving.
I first made one like this based on a book I had when I was a mere youth.

It is a modified sheepshank


After 5 loops (6" long") are made you begin a sheepshank but complete an overhand knot by placing the end of the cord through all five loops and pull tight. Repeat at other end. . The source for the sling is "Whittlin', Whistles and Thingamagigs" ISBN 0-8117-1882-2. Tony

Ammunition? That's a nice sling, but I think cartridges would drop through between the strands. Maybe OK if it was in a box. But ammo would probably be more secure in your pockets than in a sling.

I'm with Haertig...once you have made this, what is it used for?

Think David and Goliath.
It is used like the intervoven sling described here

Should be useful! But did you try it "in the field"? It feels like it could untie itself under a good enough swinging stress.

Because of the layout the harder the sling is used the tighter the overhand knot becomes.

It is for a Goliath size rock. Or a sling for Goliath to kill the Hulk?

Golf balls make good ammunition

Ahhh! I feel so stupid now. I was thinking "carrying sling", like something you'd fill with loose .22LR rounds (ammunition) and sling over you shoulder for transportation.
