With the 300 Win Mag for deer, I would use conventional bullets such as the Hornady interlock or the Sierra Game king. I had a few problems with Ballistic tips from both the 7 Mag and 300 Mag. In standard calibers I love the ballistic tip but not in the magnums. The exception would be long range shooting or loading the ballistic tip down to about 2800 fps. The Nosler however is the only plasic tipped bullet that I have persoally used. I would also recommend 180 grain bullets for the 300 Win Mag. I loaded a lot of rounds for the 300 Mag and 7 MM Mag.
