Our Polish winter is also vrey odd this year. There was only a few days when snow was staying on the ground, and a little bit of the sun. A few days ago we have strong frosts, -20-30C in nights, without snow. Now there is typically english weather, wet, windy and gloomily
So it isn't a good time for slinging at all.
I like to sling snow-balls very much. It can be a great fun, but only when snow is wet. Otherwise, it is very difficult or impossible to make good snow-ball. No matter how hard you work on them, anyway, almost every time, they fall to pieces just before release. Fresh, "warm" or melting snow seem to be the best. Then snow-balls can be made very quickly, are solid and heavy enough, besides the hands don't feel cold. On a snowfight, I would only use fresh and light snow. Otherwise it would be a dangerous play.
Snow-balls are pretty good ammo for short range accuracy practices. When target is 20-30 m away, they work quite exactly. It is nice to see when they hit a wall, tree or something like that. Well, there is a problem with making snow-balls with loose snow. Then a good idea is to moisten snow a little bit in the hands with water. Last winter I was producing hard and heavy snow-balls by moistening them, and next letting them to freeze up outdoor. The balls could reach over 100 m rages.
This winter I also experimented with ice-balls frozen inside splited tennis balls. I filled them with water by sinking in a basin. They keep water, because of the underpreasure inside, and can be used many times. If one have a few broken tennis-balls and strong frost outdoors or free place in a freezer, could make them productively.
Well, if the winter is snowy, I couldn't complain of the season.
