A fist sized snowball on a steep trail which is snow covered with a hard crust, when started to roll as a bowling ball, will lose mass and eventually stop, being about half its initial diameter.

Need more snow for future studies.

Good luck on obtaining the snow. But I'd suggest your future studies will often fail to confirm your stated premise.

Bet a lot has to do with the consistency of the snow, moisture content, etc.  Not just for the hard crust, but how well the snowball adheres to itself.  

But what the hell do I know?  I hardly ever get to see the fluffy white stuff.

So is the inverse true with wet snow, that a fist size snowball will gain mass and end up a huge big snowball like on that one car commercial or like it shows in cartoons.

Well, I can only work with the snow that is present.  It's possible I can run more tests this weekend on different snow, but it depends on if it snows before then (actually quite possible) and if I go somewhere that has steep trails safe enough to roll snowballs down.

Still looking for the right snow.

Dry powder, when formed into a fist sized ball, as well as could, may roll a good distance down the trail, when started as thrown as a bowling ball or rolled on the ground, with no obvious change in size, eventually coming to a stop due to minor terrain features.

Forming a twohand sized snowball leads to the same effect, no change in size, but it can roll hundreds of feet down the trail before eventually coming to a stop.

Need a wet powder I think for the (hopefully) interesting ones.
