Good info Blackelk. I will debate the less than perfect shot theory though. Less than perfect shots are shot oppurtunty's. If using the good bullets and knowing your gun, many less than perfect shots are very deadly when putting the shot on its mark. You said, you've guided 25 years, biggest complaint guides and outfitters have is the hunter is either out of shape or cant shot. The problem lays behind the gun, not the gun itself. Naturally, got to have common sence.... Each gun has limitations on shots depending on shot angle with the distance of the animal for that perticular shot, and another limitation is the hunter him or herself. Each person should know what there limitations are before pulling the trigger.
