I built this parts set in .54 caliber a year and a half ago. See Gun Building, Herb's Post 145 (my page 6 of posts) January 04, 2016 "I Built a Left-Handed T.O.W. Kit Carson Hawken over the Weekend". Just click on my name here and a box will come up that says "show posts". Click on that and my stuff comes up. That stock is cut with a 14 1/2" length of pull, which is ridiculous. I built this rifle for Bob, who is 6' 2" tall with a 36 or 38" sleeve length, and we had to cut the stock to 13.5 " pull for him, if I remember correctly. He wanted the barrel left at 36". There is a photo of the cut off stock on my post 47, January 08, 2017 "Re: another Hawken done- a Kit Carson". I made a .58 flint halfstock as my elk hunting rifle and killed a mule deer with it. Think I used 100 grains of Olde Eynsford 2F. I have shot my Hawkens many hundreds of times with loads of 50 to 140 grains of powder and never been bothered by the Hawken butt plates.
