I have a 20 yr. old 700 BDL 30-06 that really shines with the 165 gr. Light Magnum. Have two buddies having good luck with the .300 Win. Mag. Heavy Magnum. If you are not a handloader it is worth buying a box for experiment. If your rifle likes them it is an inexpensive way to step up to the next performance level without buying a different rifle. Be prepared for a noticeable increase in recoil.
