You guys encounter this yet? It allows arty with the shrapnel shot (that's the advanced grapeshot, right? I dunno, I don't use regular arty.) to fire far beyond their 400-range.

I believe the player just has to ground-fire the target, even if its outside the 400 range, and the arty shell explodes in the air, and sends the little musketballs all over the place way beyond the 400 range.

I've seen arty with 400-range (24-pnds) fire 3/4 across the map doing this.
