Why do anything with the stock? Guns need to be cleaned and preserved but very seldon should be refinished. To repair and clean an obviosly abused and neglected firearm is advisable, but to refinish? Very very seldom should that be done. If you sand out the dents and dings you will severely alter the stock and metal fit, reduce the guns value, and most importantly remove the guns history. Who knows those gouges could have been inflicted by a rouge unicorn. I would suggest a new factory buttplate, bullseye, and swivel, then a light walnut stain in the gouges and leave it alone. Many times a simple application of a good gun oil on the stock scratches will make them less noticable. These stock inperfections are minor and actually gives it some caracter. If you remove by sanding the original finish from the stock nobody makes a product that will return it to the factory finish. Rejoice in the fact that this rifle, unlike others, has been there and done that and has the battle scars to prove it.
