Regarding two rifles, if you are carying the heavy rifle and you spot something worth breaking the tracking on what made you carry the heavy in the first place, you have two choice; if it is close, shoot it; if it further away swap for your light rifle which your tracker is carying. This works remarkably well.

It is also why the light rifle is best a bolt rifle. It can be safely carried by the tracker with an empty chamber but full magazine. If the game is far enough away to warrant the switch, it is often far away enough to allow for the switch, and then chambering a round.

Bramble,

Why not two scopes in seperate rings, each zeroed for one of the barrels? Many different mounts return to zero well enough for general hunting, if not leopard hunting. Talley for example. Of course claws would be the best.
