If you want to do a better job on the stock, here is how I do it. Others, I am quite certain do it other ways.
1. I apply a single layer of aluminum (.003 thick) air conditioning duct tape to the front and rear of the receiver and tangs and with a sharp knife trim it back so it is on the surface and not folder under where it will interfere with the stock fit.
2. Put the stock back on and with 220 grit paper backed by an "art gum" eraser sand (with the grain) the area where the wood contacts the metal. The aluminum tape will take quite a bit of abrasion and this will keep you from over sanding the wood so it will be below the metal.
3) Go back over this same area with 320 or 400 grit paper.
4) Removed the wood and sand it for the entire length with 220 grit. Don't go back over areas you have previously sanded near the wood. Again sand with the grain.
5) Take a wash rag, wet it and ring it out. Double it over and lay it on the stock and using Moma's iron steam the stock. God over the dented and scared areas two or three times. This will raise the wood in the dents and help some with the scrapes and scratches.
6) Now take your 220 paper and backed up by a wood block or sanding block sand out as many and much of the dents and scrapes as you can. Be careful not to dish out any areas. This may or may not remove all of the hickies depending on how deep they are.
7) Save the sanding dust!!!

now mix up a little Brownells AcraGel and add the sanding dust. When this has stiffened up a mite place it in the remaining scars. It should be enough to sand up over the surface.
9) You will need to do this twice, once for each side of the stock.
10) When the Gel has hardened (give it a full 24)hours, sand the stock (again stay away from the areas sanded next to the metal) with 320 or 400. Oh did I mention to keep the butt plate on the stock so you don't round over the edge of the wood. You should have a nice smooth, hickey free stock. Yes you will be able to see the filled places, but nobody coming by on a trotting horse would notice them.
11) Now you finish the wood and Tru-Oil is a great product.
Yes, this take some time, but when you are through, it will give you great pleasure every time you look at the rifle....or maybe not...depending on how you consider such things.
