A properly maintained and correctly loaded muzzleloader can be about as accurate as any modern rifle, with the possible exception of a topnotch benchrest gun. In addition, with the right bullets, muzzleloaderscan have plenty of range potential as well, except that due to their relatively low velocities, they have steep trajectories. This means that to hit your intended target at extended ranges, you have to be very good at range estimation, and you have to do enough long-range shooting with your rifle to know its' trajectory precisely. Here I'm talking about ranges greater than 200 yards.
During the Civil war, both Union and Confederate snipers are known to have madekills at ranges of up to a mile or so! For this work, they used heavy barreled target rifles called "slug guns" which were equipped with false muzzles for precise loading, and telescopic sights!

British Wall Gun (727) PER THE RIFLE SHOPPE:
This gun has a 54" tapered round barrel with a 1" bore, it also has a lug on the barrel for a pivoting swivel yoke, and they are quite accurate.
There is a letter on record that Washington had a few wall guns made up that were capable of hitting a sheet of common writing paper at 600 yards.[/i][/b]
