100-400 or so
Yes. I've heard of it.
The value of a Thompson 50 cal muzzel loader K7846 is about $400.
I bought one at a gun show for $85.00.
Percussion cap ignition in muzzle loading firearms was introduced around 1830.
$1,800 I can't imagine $1,800 for a T/C muzzle loader! This is obviously not the inexpensive Renegade Model which as used brings around $125 and like new might go for $250. Is this 54 caliber percussion Hawken Model a custom shop or commemorative model? <><><> Agree- depending on condition, these sell for around $200.
T/C Renegades are selling for between $150-200. Excellent rifles, but they are being overlooked in the rush to buy an in-line 209 primed rifle. Market for them has been down for past 3 years.

You can order direct from Thompson Center or Dixie Gun Works also Midway USA. All have on line stores. You will need to know the model and caliber.
While these are very well made firearms, the value of the traditional sidelock rifles has decreased as in-line muzzle loaders have become more popular. These can be found in very good condition for about $250. I shoot a T-C Hawken in 50 cal, and it is an excellent rifle.
