Yes, absolutely.

But the GURPS rules as written have both the sling and staff sling using projectiles of less than 1 oz., which means that they are about equal to a heavy black powder pistol ball.

I want to correct the sling rules (in the other thread, which is probably a more appropriate forum for this discussion, eh?), so that light sling projectiles are good against unarmoured people, but don't even penetrate heavy clothing*, but the only way to use them against armoured opposition is to use magic, alchemy, in some cases chemistry or, extra heavy projectiles.

*Which experiments bear out.
