Re: Best slug gun scope?
If you're only going out to 125 yards, both are more than enough. I would recommend sticking with lower power in case a deer shows up close.
I picked up a Nikon Slughunter in 2-7 this fall, and that is more than adequate. I found that most purpose-made slug gun scopes are built to a price point (low) and there aren't many that are exceptional.
