Curtis, this rifle demonstrates that you have the skill to create a truly fine rifle. But you have started with a very poor precarve, as far as architecture is concerned. Fahjen took T/C's horrible "Hawken" stock, and added their own ideas of what a rifle should be. There was a lot of wood that needed to be cut away, and some of us have commented on that. The most glaring problem is the wrist/cheek piece area. I had to check out the lock side to see if it was a roll-over cheek piece! The shape of the cheek piece is not 'wrong', but it could have been made better if it had been reduced in length from the butt plate, narrower from the bottom of the butt stock, and much much thinner at the comb. That being said, most plains rifles out of St. Louis, Hawken's rifles included, did not have a thin sharp transition from comb to wrist. It was a little bulbous and smooth, but only about a third of what you have here. The wrist - right from the breech back, the wrist needed to be shaved down until finally at the transition to the comb, about 3/8" of wood needed to be cut away. That would have given you a comb that was about 1/2" too high, and would also need to have been cut away. the result of all that would have been a reduction in the slab-sidedness of the wrist, the thickness of the lock panels top and bottom, and a much more pleasing outline. Don's comments on the lower butt stock lines is accurate. That area is nicest if it is narrower at the butt plate and parallel to until it comes to the for'd end of the trigger plate. Sometimes, the very back end of the toe plate might curve in a tiny bit to the butt plate's tip.
Precarved stocks, for the most part, leave enough wood for the builder to make just about anything that they wish, but look best when a lot of the wood has been taken away. Even Chambers stocks leave more wood than you need - forgive me Jim - my own opinion naturally. but nowhere near as much as that old Fahjen stock. One thing in their favour though - they used good maple.
All this might sound pretty negative, but I sure don't mean it to be. I hope that you'll think about these points and try to incorporate some of them in another build, because you have lots of ability as demo'd by the workmanship in this rifle.
