I finally finished my second Carson Hakwen, both from the stick. A very close copy scaled from a full-sized photo of the original.
Top is my Jim Bridger copy, also made from the stick, with a 1 1/8" straight barrel. The top three rifles are .54 caliber. Next is my Carson rifle just finished, with a 1 1/8 to 1" tapered barrel. Third is a Carson with a 1" straight barrel, otherwise also a close copy. Fourth is my .58 flint plains rifle (I don't call it a Hawken). Last is a .40 St. Louis Hawken squirrel rifle.
I did not "age" the Carson rifles. The latest one was browned with Laurel Mountain Forge Barrel Browner and Degreaser and soaked in boiling distilled water for each of the five coats, which turns it more blackish than blue. The breech plug, tang, lock, butt plate, toe plate, trigger guard and plate, escutcheons and keys, nose cap and entry pipe were all heat blued. Same for the third rifle, except the barrel is blued with Brownells Oxpho cold blue.
The top two and the flinter are too heavy for me to shoot off-hand, but I probably will shoot my newest Carson rifle in Jim's Peep Shoot Sunday. I can still do OK with the 1" barreled Carson. I have lost interest in .40 caliber rifles, only having three I have built.
The entry pipe is cut to the same dimensions as the original. The ramrod is a full 1/2", slightly tapered to larger at the front rod pipe. Stain was Lincoln's dark brown oil leather dye, which I expected to be very dark, but it is not.
Of the 20 some Hawkens I have built, the Carson rifle with a 1" barrel is my favorite. I will probably draw an antelope tag this year (have six points), and am considering using a 32" Rice .50 Jaeger barrel, which is swamped, to build another Carson Hawken for hunting. Yes, I know this was probably never done, but I just don't have the muscles any longer to hold heavy rifles for off-hand shooting.
