Jedgreen,
Apply a good heavy coat of wax, Johnson's Paste or other decent wax and let dry to a haze..
Aapply into the checkering and IF you are of a mind to, remove barrel action from stockworks and do the hidden surfaces of the wood beneth barrel action mag well etc etc also.

You can buff off with a old tee shirt, or just leave as is for a non glare surface.

Take some wax and a rag with you so you can redo the treatment in the field after drying it IF the rifle gets really wetted down.
I also wax the metal on my rifles with Johnson's paste wax..
Not water impervious, but does help shed water or rain during field use.Jim
