I wore one out while a teenager. I have worked on several since.
The good: The barrels were very good. The rifling was less deep than modern made patch ball barrels and this was good thing. They shot balls and conicals very well.
The bad: The stock on the Hawken is too high in the cheek for iron sights, it will bruse the cheek of many guys. The stock design overall was to chunkie, weird looking, and it had zero historical basis. The cap locks worked OK. The original flint locks were pure junk. All of the steel parts were rough castings. The construction practices were strictly modern, screw on thimbles that stick up from the rib, screw on trigger guards, for instance.
The breech plugs were indexed by brute force instead of fitting them. That caused the threads to be compramised on a few guns. It also left a gap between the internal shoulder and the plug snout on some guns. That created a fouling trap. It also caused some guns to grab cleaning patches. TC did not understand the importance of fitting the breech plug properly.
Overall they were a "price point gun". They worked. They were priced low without taking the quality cheapness so far as to make the rifle problematical. I would put CVA and Traditions in taking the quality cheapness too far.
There are lots of TC fanboys out there. That is great, have fun, that is why we enjoy the hobby. I woud argue that many of them would raise their standards if they were educated on what a quality rifle actually is. Some do not care and that is fine too. TC made a reliable rifle.
