What I personally do, is I get the lock and barrel inlet, I cut the end of the butt to shape for the profile of the butt plate, then from then I inlet the butt plate. The stock is still square at this point (I've already drawn my plans out on the stock and cut off the nessecary wood) once the buttplate is inlet I star shaping the butt stock, up to the wrist and give myself about and inch or two from the lock mortice area. Once that's roughed out I get the lock mortices shaped up and the tang area to the profile I want. I keep working my way up the gun in segments. I'd highly recommend not shaping the forestock untill umyouve inlet your ram Rob thimbles, otherwise you may have jiggly thimbles when it's all said and done.
