Expert archers show how to hit a target that's behind something

If you do you should probably only try it at a completely empty range. Lots of drag on the back of an arrow makes the arrow stable. Putting lots of drag on the front of an arrow makes it unstable. That arrow could go all sorts of places you wouldn’t expect. I’ve read some scary stories about people bareshaft testing (arrows without fletching) broadhead hunting arrows where the arrows went in some unexpected directions - but that isn’t something I’ve tried, so I don’t know just how likely that is to happen.
