I am not a pro but I would imagine if the dough is soft but not gooey it should work just fine. If you squish it in your hands and it holds a shape, it should be good. A spritzer recipe is soft. It is not sticky, just soft enough to mush into the tube. Ido not recommend chilling a dough to be used in a tube. You would have to leave it out too long to soften enough and if you have egg in the recipe it is not a safe practice. If you have to wait to use it, put it away flat as a pancake so it will take less time to soften. You can mush it between sheets of waxed paper.
I never chilled a cookie gun dough of any kind.
