Acro LD-1 sling description:
LD-1 stands for Leather pouch Dyneema cords 1st generation. The LD-1 sling was used for most of my long range hits.

The features of this sling are:
•      a very durable cupped leather pouch that can sling a great variety of ammo shapes
•      dyneema cords (the most abrasion resistant material I have used)
•      Acro release. Sewn leather release for light grip, powerful shots and high durability
•      a Leather finger loop for comfort

Attention:
Every time you use a new sling do it at a safe place in a safe way. Don’t sling near other people or animals. Don’t use a sling without a warm up. Increase the speed of your shots gradually.

it's plenty strong for slinging. you can rip it if you use it for stretching or pulling heavy stuff.

after a lot of use with abrasive ammo it gets thinner on the leading edge of the pouch. This weakens the leather at the connection and can rip. This can take more than a year even with abrasive ammo and no leather oil.
