Mule Brain,
Hawken looks good to me. You are going down the same road I did. My first build was a Hawken rifle. To me, they are much harder to build than most rifles because of the complexity of the breech/lock area. Hang in there, things get better with each build. I am finishing a full stock now and it has fought me every inch of the way, but I think I have just about won the battle. The finished product will give you a lot of satisfaction.
