Got a 3-9x40 Conquest on mine, but have killed deer with a previous 4x32mm.
Used same rifle and Elite 4200 3-9x40 at 5x to take pronghorn, and have killed WT dere here in Tx at 4-6x with it.
In fact the only thing I have killed with it at 9x has been priarie dogs and paper. So 3-9x has been plenty for medium game.

Scotty, what sling is that on the Mash?
