You said you're mainly a bow hunter and have 2 sluggers already. I've been a shot gun hunter all my life. I've got three "slug guns" and would recommend a NEF Ultra Slug or a good ole fashion muzzleloader against any pump, semi auto, or any other make or model of slug gun out there. There simple and effective. And they can straight up bust anything out to around 100 yds. I wouldn't go with any other. I have an 870 and an 1100 and both are good guns but just don't match up to the NEF. 1 more thing, I'm not saying it couldn't happen, but more than likely, unless you have an ultra ultra accurate setup a 200yd shot is going to be out of the question for a slug gun ( or most muzzleloaders) so if that is what you're wanting I suggest a centerfire rifle. But definately check out the NEF guns.
