I have the 500 too. Nice gun.
Used to just keep it for the skunks and woodchucks that made the mistake of using my yard as a mess hall, but now hunt with it here in Putnam.
No scope and I don't own a dog, but it's kept me fed with plenty of Grouse, Pheasant, and squirrels. Almost had a shot at a Buck last year, but I dropped the chair I was carrying before I could bring up the gun to shoot. What can I say...I like to sit comfortably.
