I will partially take issue with trade guns being of inferior quality to a Brown Bess. I have one HBC trade gun from around 1800 and while it was missing the lock when I got it, the inletting for the original lock showed that it had a bridle on the tumbler. I have a much more modern gun from 1875 and used to own a Barnett percussion trade gun (1885) and both had excellent locks. The partial issue is that I have a NWC trade gun @ 1780 to 1815, now converted to percussion and its lock is a cheap one with no bridle on the tumbler I had a chance to look inside another HBC trade gun of the flintlock era and again a bridled lock of reasonable quality. It would not surprise me if the quality of the NWC trade guns was upgraded as the company progressed into the 1800s
If I were going to travel any distance with a gun, in that time period, it would probably be a trade gun and almost certainly not a Brown Bess. The bess is heavy and requires a lot of lead and powder. A 60 cal trade gun uses 1/2 the powder and 1/2 the lead, both of which had to be packed along with you
