RE: Dedicated Slugger vs. ML
I would go with the muzzleloader. 1" groups at 100 yards are fairly easy to accomplish with the ML, and they hold well beyond 200 yards unlike most shotguns. Cleaning the ML does not have to be too difficult either, just get some good supplies and a simple design. The shotgun will probably always be easier to clean though. Still for the weight and the accuracy the ML is the way too go.
