RE: 308 Win
I think both the Winchester Supreme Ballistic Silvertip 168gr and the Federal Premium Accubond Nosler Partition 165gr would be pretty similiar. Let me double check some velocities though...
Winchester Supreme 168gr
Muzzle velocity: 2670
Muzzle energy: 2659
Federal Premium 165gr
Muzzle velocity: 2730
Muzzle energy: 2730
My Savage .308 seems to prefer Federal ammo, so that's what I feed it. Federal American Eagle 150gr for plinking and Federal Premium Nosler Partition 165gr for hunting.
