Gunwriter from Oz, I haven't read all of the post in this thread but IMO the best bit of information in the entire thread has got to be your statement about not getting bound up with "generic" information and instead letting the rifle tell you what it wants.
Being human, we tend to be a bit pompous at times. We know everything, and tend to make up the facts instead of relaxing and just observing them. That is why I recommend learning what your own rifle's prefer instead of dogmatically insisting that it is going to like .020" or .050" off the lands.
Let the rifle tell you. It will also go the the trouble of proving it.
