For some, those would be good choices but not for all.
As you know, the kits sold by Lyman, Traditions, Pedersoli and the other large companies are basically factory guns which were removed from the production line and require little more than sanding, applying a finish and screwing them together.
All of the necessary machining has been done to them.
The "kits" offered by Track of the Wolf, Pecatonica River, TVM etc. are really just a box of roughed out or as cast parts (except for the lock).
Many of these do not have the breech plug installed in the barrel, the dovetails for the sights and barrel underlug machined, the screw holes located, drilled or threaded.
Actually, these more advanced kits take almost as much work and knowledge as making a longrifle from a barrel, breech plug, trigger, lock and a pre-carved stock.
The only real difference is the size of the parts.
Many of us find building these advanced kits to be a interesting and rewarding hobby but doing this is not for those who don't have a fair knowledge of metal and wood work.
That's why we added the Gun Builder's Bench to the forum. It provides a wealth of information and knowledgable builders for the new builders.
