Leather scabbard bolted through the left side, butt by your left hand, of the hood works great if you want to be able to grab it on the go.
I usually have mine in a scabbard on the right side, pointing forward and along the tunnel. Couple soft bungees to keep it tight.
If it's an open case (leather scabbard) you need a scope cover. If it's zippered soft case it might be ok, but snow might get in there.
Sorry, I don't think I have any pictures though
