mauser06: Thanks for the thoughtful reply. The benelli M1 Field Slug Gun is what I was considering (as seen here:
Http://www.benelliusa.com/firearms/slug.tpl). Yes, I agree that it is wise to sight in before going afield and am sure many hunts or shots were spoiled by those that did not take the time. I suppose I could use some quick - release mount for the scope and get used to shooting with the rail in place.
bigcountry: Well, that' s not a glowing report on the 11-87, some searching shows that they can be finnicky - one of my concerns.
dvdegeorge: Thanks for your comment about dedicating a single gun/game and I agree in general but felt this dual use would be ok. I used my old 870 with difft barrels and was very happy, maybe I am expecting too much but what was of greater interest was your comment that the " CANTILEVER BARREL IS NOT VERY ACCURATE BECUASE OF BARREL GOING ON AND OFF NOT IN SAME POSITION EVERY TIME." Is this a significant issue?? I usually remove the barrel for cleaning at least every 3-4 use. Is this a problem with a cantilever mount that is attached to the bbl?? I would suspect your comment would apply more to the Benelli with its scope mount on the receiver and not the bbl. Somthing I had not considered
