I enjoyed the movie "Broken Trail" so much that I got the book out of the library. Like most novels, it's even better 'cause the 'pictures' are better .... ;>)
The rifle carried by 'Tom' (Print's nephew) is described a "cut-down Remington Rider", no mention of calibre. This being the post-Civil war era, I was wondering what pistols would be used. I couldn't recall from the movie.
Well, 'Tom' has occasion to shoot a lame horse and he took from his saddle bag, "an old La Mat .44". That may not be the correct nomenclature, but it's a welcome change from the usual "Colt horse pistol" or "Dragoon Colt". After using it, "Tom rewrapped the revolver, first removing the spent cartridge and replacing it with a new load."
Really? OK, he had a Le Mat conversion, as there would be no 'cartridge' to remove from a percussion gun. Still a good read when it's -44C out there ..... ;>) -40 is where Fahrenheit and Centigrade meet. Starting to feel 'crisp' out there.
