In the US? Few and far between- using beanbags to represent ranged spell/alchemy stuff is common, and the majority of the systems can point back to "high fantasy"/D&D for their ancestry, and if you really want the big blame for it- it's Darkon/Amtgard. When people started games, they wanted a magic system that was a bit more complex but easier to deal with as far as what you had to carry around, since it's a goddamn pain carrying a bunch of balls around to chuck at people.
People experimented a bit. In the early 1990's, instead of beanbags, they used "spell packets" that were made with (literally) kleenex, corn starch, and a bit of scotch tape. Of course, these couldn't be re-used after tossing them and absolutely sucked in wet weather. People started taking small cloth squares, filling them with birdseed and either duct-taping or sewing them shut. This worked out well- you could carry as many as you needed easily, they survived weather fairly well, and if you lost em in the woods, the animals loved the snacks.
And that's why most US systems have people chucking beanbags at each other for spellcasting and calling spell names and effects out.
