Slings can progress in the sense that, the stronger you get, the heavier stones you can carry which in turn requires a sling made out of ever sturdier material.
Material failure is pretty much never going to be a dominant concern with slings. Heavier stones, similarly, do not necessarily offer any clear benefit: Kinetic energy increases linearly with mass but quadratically with velocity, while momentum is linear for both. There is a point at which you have enough mass to overcome air resistance and after that, you're losing out on kinetic energy, and even a small child is capable of carrying a fair number of stones of that weight class.
So there's not really much physical mechanism for progression, other than gaining ammo types such as magical, biochemical, or explosive ammo.
The thing with slings in sci-fi is that any sci-fi enhancement you can apply to a sling tends to void its potential, or be applicable to better weapons, like guns. In a modern or sci-fi setting, the entire benefit of using a sling is the ability to sneak it into places and then launch things that can be obtained on-site or not seen as weapons. If you can smuggle unusually deadly things in, like explosive, biochemical, or even nuclear projectiles, you can smuggle an actual gun as well.
