 One pétanque technique which may not be obvious (or relevant to your requirements) is to give the balls some backspin, so that they don't roll on from where they land.

I think the use of beanbags (like cornhole) would be more reliable though
likely not allowed in your game.
I still find the water balloon an appealing choice of projectile;
it self-destructs on impact (leaving a liquid that dissipates,
instead of some "artifact").
It's also *fun*!
While I suspect making repeatable masses would be easily
achieved (fill to a weight/volume of X), I am not sure if
they would tolerate the sorts of accelerations required
to lob them 20 ft in a high arc.
[Note that one typically tosses water balloons gingerly,
lest they break in one's hands!]
I'm not sure making a mechanism that can have that much control
over the launch action is any easier than one that is more explosive.
