todbartell said:why waste all the capacity and potential that a 300 Win Mag has by handicapping it with a light-for-caliber bullet??
If I owned a 300 Win Mag, I'd feed it 168 gr Barnes TSX at a low end weight, and/or a 180 gr Nosler Accubond...
150's shed speed faster due to their lower BC, and penetrate less due to their high impact speeds and low SD.
Better off saving the 150s for a 300 Savage or 308 Winchester.
