RE: .300 Win Mag - fav cartridges?
My wife & I both shoot 300-win mags. Her' s is a Remington model-700, mine is a Ruger M-77. Both rifles shoot Federal Premium 180-grain Nosler Partitions very well. I have killed at least 10-elk & 30-deer with this rifle & ammunition combo.
Pick up a box & let us know how they shoot in your rifle.
