Corrected entry: Jeremiah finds Hatchet Jack frozen to a tree and begins to approach him. In every close-up shot of Hatchet Jack, you can see Jeremiah's rifle resting on the tree behind him. The rifle is then absent during shots from further away as Jeremiah approaches. Jeremiah does not place his rifle there until he reaches Hatchet Jack and begins reading his note.
Corrected entry: In the scene where Jeremiah attacks the Indian camp, he jumps off his horse with a Hawken muzzle loading rifle in each hand and shoots each as he is running toward the Indians. A Hawken rifle is very heavy and kicks like hell making it virtually impossible to pull off such a feat.
