Have a 1993 New Haven Model 70 Stainless Classic in synthetic stock (308), and will a McMillan Edge in wood reduce the weight and by how much? I have a Winchester 1992 catalog and it lists the Model 70 classic stainless in synthetic 308 as 7 lb. Have it now mounted with scope and it weighs 8.3 lbs....can I get it any lower with walnut wood?
