Thought about a savage smokeless muzzleloader? If its legal in your state(some only gun season,some both gun and muzzleloader season), and if you are willing to put in alot of range time 325 yd shots are very doable. With only a little work its a 250 yd setup out of the box. Point and shoot out to 200 yds. Beats any slug gun I've ever seen, and for about $600.

Justanother option to think about.
