If my reading is correct, the Cabelas hawken is made In italy. I have an extremely similar gun in 54 from the same factory. It shoots well. However, for fit finish and traditional look, I have to agree with others, go with the Lyman Great Plains Rifle in 54. that couple extra inches of barrel isn't that much heavier, gives you better sight radius and slightly more efficient use of powder. If you can swing by a place that sells a selection of muzzleloaders so you can actually shoulder the gun. or even more, go to a black powder match somewhere around home and get an idea of what others are shooting and most folks will have no problem letting you get the feel of various different makes and models. I have had traditional guns from TC, CVA, Traditions, Lyman, Euroarms. and others. If you can find a used CVA big bore Mountain Rifle, (not their hawken) it is worth it's weight in gold. Otherwise, go with a Lyman. Lyman actually fits most average to tall height men better than the TC guns.
When I went from modern stuff to muzzleloaders, I had some preconcieved notions about barrel length, and weight and handling. Mostly wrong as rain. 28 to 32 inch barrel is best for hunting. I currently use a 5ft long rifle in 50 caliber that weighs less than a TC hawken and is better balanced. Seems impossible but it isn't. Sights on muzzleloaders come in all varieties. however, good fine sights that are easy to line up in a snap are a bit hard to find on many models. Some front posts are so wide, they could obscure a barn at 100yds. On others the rear sight notch is too small. If you can go shop the guns in person, you will see what I mean.
