FWIW the Brown Precision synthetic stock on my 700 BDL LH .270 is definitely lighter weight than the original walnut stock. I have two Browning Stainless Stalker rifles that have the original Browning (brand) synthetic stocks and 26" barrels. Both rifles seem lighter than they would be with walnut stocks. Synthetic will never look nicer than decent walnut.
