A customer came to me wanting to know if I could build a stock that was 2 pounds or less.  I used the Koa because it is a lower specific gravity than Walnut (which makes it lighter) and stronger. I was still able to use pillar bedding and keep the weight down. The fore end could be shortened to reduce the weight even more. Since the drops on a silloute rifle are different than a prone rifle, I kept the pistol grip from the prone rifle which is comfortable and tried to come up with a higher cheek piece  and more drop to the buttplate.  All of this required lots of hand carving.
