Sanding dust from the stock and mixed with epoxy or glue works for me. mask off the area so it doesn't go where you don't want it to go - just the holes/chips clean the wood to get the oils out first. I have used the Minwax max performance wood filler stuff -it will take stain but not real well. I have also put some of the brown dye from a brownells glass bedding kit in it too.
