Thanks Steve and Mike for your help.

So, sounds like I should start the process by finding or reloading (which I do) a load that will shoot well with the original iron sights. Then I can of course adjust the scope to match the load that works with the iron sights. If I am really lucky the slug load (2.5" Brenneke's) may also shoot well with the iron sights but if not possibly try some other slug loads or reload some various slug loads. Actually, though I already know the Brenneke's slugs shoot quite high using the iron sights but I might be able to find some slugs or reload some slugs that shoot closer to the iron sights.

It may be awhile before I can get out and try this. We are in the middle of our short two week deer season so not at the range much right now. Trying to hunt when I can right now.

Thanks,
Ron
