MIdeerhunter, your new scope in question should be fine. Good field of view for a shotgun scope.
If your gun seems to like it then that's what is important, that plus range time to get familiar with the gun/scope combo and you're ready for the field.
Yes, it is possible to overtighten scope rings. I have never done it myself but it can happen. Good and snug works best for me. Some folks use blue Loc-Tite on the mount screws, I never have but don't have scopes on my heavy recoiling guns.
There are lots of knowledgeable folks on this board who will add to or correct anything I posted here. Give the guys a bit of time to find and read your post and you'll get some good advice.

Good luck this season.
