Owen, I measure guns for their objective handling characteristics; much as stock fit dimensions are measured. If you measure the weight, tetter-totter balance point to (front) trigger, moment of inertia at balance point (unmounted swing effort) and calculate moment of inertia at butt (mounted swing effort) you have a complete picture of the guns handling. The only trick here is to work out how you actually wish a gun to handle for which purpose it will be used.
Considering all shooters do not use the same stock dimensions, it seems likely that all shooters will not require the same handling.
Post back if you have questions. Happy to discuss.
