Sounds good in theory but I am not sure it really works that way. This is based on installing a large number of laminated stocks on M-14's and M1A's in the late 80's and 90's. Fajens and Bishops mostly but if I remember correctly Rutland was the mill most of the laminated blanks came from. When finished with True Oil you could see expansion around the butt plate as the summer got more humid. After switching to the West Epoxy I stopped seeing any expansion or contraction. For EIC service rifle matches no sighters are allowed. The epoxy gave an extra level of confidence that your 600 zero for that range was always the same. For those that don't shoot NRA Highpower zero's for that range means physical location and altitude. You keep a book on your zeros for each range and yardage. My 600 home range yardage zero will be different than at the Nationals at Camp Perry or the All Guard matches at Camp Robbinson.
