Big Bore Doubles are the hammer that kills when used correctly.An instant 2nd shot if needed.

Ideally, the 600 NE is better than the 577 than the 500 etc.

In reality to be effective a 600 must kill better than smaller calibers and still serve its purpose of having an instant second shot in reserve.

Is the 600 a better quicker,killer with non CNS hits than smaller calibers? I would have to say a qualified YES!!! Is there any dispute over that??

But is the 600 still a working Double at its carry weight and the speed of its second shot?? That's debatable. For some individuals it is not effective functioning as a working Double due to recoil and recovery time. It certainly wouldn't be for me.

What Double do forum members think is the maximum useful working Double gun for carry on a DG safari and also fills your need for a stopper?
