All the glue will be lost in acetone. You will have to do it all over again. In my experience even in just acetone the stock will swell slightly but will go back to original size after a week or so. There is no guarantee that it will but all of mine did. Alcohol absorbs water (humidity) and will swell the wood more but will also return to original size so don't sand if at all possible and certainly don't sand the butt end unless the pad is on or you will wind up with rounded edges. I don't use alcohol, as I said, and that is one of the reasons.
