I hope to add to the slug gun topic when I get this gun package put together and see what it will do. I have access to long ranges for sight-ins. Opinions in the forums are simply that. Some are based on actual experience and others on plublished articles. Hopefully the blend of both contributes to good advise and information for those seeking it. I think here we do a pretty good job on both fronts. With hunting season over now I have time to get my slug gun project completed. Well see what the 870 can do!
