thats understandable.
IIRC how it was explained to me was that the prohibition on placing your own stands was to prevent people from dynamic shooting drills on the static (non-3 bermed) ranges
i get it in a way... though for pistol, id rather set the distance as i wish. heh
i suppose its not an issue so long as you are quallied on the 3 berm..
*shrug*
