I'd like to know more about the Trade Gun. Now, most of these were .69 caliber? And what were common loads besides a round ball? I see in Muzzleloader magazine that the "French Fusil" trade gun is very popular among frontstuffers today. Why is this? Is this a "jack of all trades", able to take big game with a round ball and small game with birdshot, and medium game with buckshot?
