Almost any of the current mass produced muzzleloaders are lethal out to 100 yards once a load is worked up. From what I have READ about the rifle, with some good optics, it will be a good all around shooter.
But consider the cost of the rifle and compare that to the cost of other rifles in the same field. Yes a Knight or T/C is a excellent quality rifle. But that's not to say that a Traditions is any less serviceable. If your looking for the muzzleloader season of Wisconsin, and not countless weekends on the range having fun, then it will probably work for you.
I recently purchased a CVA Optima with a stainless steel fluted barrel, and quick release breech plug for a little over $200.00 at Mills Fleet Farm in Wausau. They might have the same thing at a Farm and Fleet. I like that rifle much better then the buck-stalker, but in reality they are very similar.
