www.ultimatefirearms.com and look at their muzzleloaders. I have one with a burris balistic scope and is is everything they claim. There is zero problem shooting decent groups at 300 yards. They brag of countless kills at well over 300. I don't doubt it, I just have never tried. His secret is his primer system. It burns all of the pyrodex virtually at once. The gun is also very easy to clean. Two times with a damp patch and you are done. It is all I carry in Illinois during the shotgun season where we were always hampered with the minimal effective killing distance of a slug gun. I know they are pricey but they are well worth it when Mufassa is standing out there at 300 yards.
