This is a metal shell filled with 0.5 lbs. of smokepowder ($100). The casing is either local bronze or imported cast-iron cast in two parts, or it is segmented iron meticulously assembled locally, with lead and wax used to solder weak points. In each case, there is a +3 CF, either for rare expertise, foreign imports during wartime or valuable local metal (with local merchants selling it to the PCs at a significant markup). The casing is otherwise treated as a the smallest metal box from LT, with the ovoid shape (and space for a fuze) counting as Heavy Compartmentalising (Weight x1.2, CF +0.5), Rugged (Weight x1.2, +1 CF) and Expensive (Weight x2/3, CF +1). This comes to $45.5 for the casing, which weighs 0.384. We'll assume that we fill the extra space with scraps of something free and heavy (stone, probably, or glass fragments), for extra fragmentation, and round the whole thing, with fuze, to an even $150.

Go with glass. You get cutting shrapnel instead of crushing or piercing fragments. This becomes even more lethal if your mages know how to get creative (even if only for a limited number of these).

Using a slightly scaled up case, which adds ca +50% to Weight (0.768 lbs.) and +100% Cost ($91) of the casing, this leaves space for more fragmentation material in addition to the unchanged 0.5 lbs. smokepowder charge ($100), which makes for a much more effective weapon, albeit one harder to launch long distances from a sling. Using scrap metal, this rounds to a nice $200.

The more shrapnel, the better!

Mixing lead designed to fragment with purpose-built sharp metal shards, this is otherwise very similar to the above weapon and hardly more expensive for the increase in effectiveness. It is, however, heavier.

Heavier also means less problems with wind, which increases accuracy.

Packing a casing of the same size as the 2-lb and 2.5lb shells to maximum capacity with powder and lead bullets, this is a very effective weapon, but difficult to sling far enough to be safe from the fragments. Fragmentation damage is pi instead of cut. Often used with a magical fuze (+$250).

If slinging this far enough to not kill yourself is a problem, load dozens of these into a catapult and bombard the enemy camp.

With the iron/lead/bronze wire wrapped around them, probably. The resulting shrapnel is just a bonus with those.
