I recently purchased a Merkel 961L 30-06/30-06/20ga. As my eyes can no longer adequately see iron sights I am going to place a scope on it. I am considering a Luepold 1x4X VXII or a VX3 1.5x5X. The VX3 reportedly has better low light characteristics so that would be my choice but I am concerned my ability to judge the lead of a bird will be compromised due to the 1.5 magnification. I have never used a scope on a shotgun before so I am in the dark about doing so. Any advice or thoughts would be appreciated. Thanks
