I have never shot air pistol silhouette, what are the distances for each of the targets?

Anybody know anything about the scout? Just came across it.

Do you guys have to put any filler in after powder with those light load? I use H110 which is basically the same but use 13 grains and a speer 130 bullet. I would like to lighten my load for less recoil,
