Much like Chris you are probably right. That said, you could run it with one static shooting position and orienteering points located away from the firing direction. Competitors are required to navigate to a marker then return to the shoot position before heading out to their next marker... If the entire course was encircled by something (road, fence, river... and shoot position fired out of the course area then you could tell competitors not to cross the course boundary. If they got lost they could then follwo the course boundary until they got to a shoot location.
Again, probably a non starter...
Pretty certain i read somewhere that shooting a .22LR to 200m mimics shooting a .308 to 900 yards or something. Certainly would boost confidence in dialing several minutes of wind.
The great thing about using the 22LR is it is cheap, they don't use jacketed projectiles so you can set steel targets as close as a few meters, steel targets only need to be mild steel and the .22LR is a reasonably level playing field for everyone. As soon as you introduce the .17s, .204, .222, .223 then everything gets more complicated.
