[QUOTE="Kennibear, post: 858574, member: 51650"] In agreement with sp6X6 the pure physics are not with total gun weight but rather with "high polar moment of inertia". Take a tiny 22 for kids and add 10lbs of lead under the butt plate and that gun won't shoot or hold any better than before. Take a good look at Biathlon guns and you will see their weight is in the barrel and the stocks are super light weight Kevlar / Carbon fiber tooth picks. With the mass concentrated at the end of the barrel the Biathlon rifle has the same "Polar moment of inertia" as a benchrest sled gun. We Long Range Shooters could apply this same approach to our rifles and save a few pounds yet not compromise the performance of our rifles in the field. I gave up wood stocks for two reasons: 1) Weather resistance. 2) Weight transferred forward by lightening the stock (higher polar moment of inertia). Works every time. A ten pound lead ball starts rolling pretty easy but a rod six feet long made from ten pounds of lead does not turn over end for end readily. Just for discussion. [/QUOTE]
