you can make a reasonable rifle from the kits .
depending on the time frame "if that concerns you at all " the two piece stock is also correct for a late percussion gun . Whats not correct is the way the they hold the stock together . There are a number of examples where the maker even used a silver plate to join the stock section just as traditions does and CVA did ..
The main problem with the traditions kits are their overall quality .
Locks are often weak . Their choice of wood for the stock is IMO sub standard and often a lower quality even for this wood type .
You will also need to watch the lock inlet . I have seen a few where it doesn’t allow the hammer to line up correctly on the nipple .
That all being said IMO if this is your first rifle that you are looking at building , they make for a reasonable experience . Some issues you can deal with , others ,,,,,,, well you just have to accept them
Here is a picture of a traditions Kentucky I recently built for the Traditional muzzleloading Association drawing . That will give you some idea of what can be done .
With this rifle the trigger guard came broken thus I hand cast a new one . Also notice that the I have gave it a side plate as well as cast a new nose cap from pewter .
The wood of the stock also does not yield well to carving and chips out easily so any caving you do will not be crisp so don’t try to get to intricate .
