What caliber is the barrel? We don't see the high comb, and cheek piece on these guns very often, but it looks nice. Does it fit you? Can you give us the Length of Pull, the drop at comb, and the drop at heel? Did you use any Cast-Off in making the stock? If so, how much? And what is the pitch on that stock? It looks like it might make a good gun to shoot Prone. Is it?
