As sunray indicated, boiler shots mean little meat damage, generally.
As the 300 has a good bit of velocity, lots of guys favor tougher bullets like Partitions, Accubonds and TSX's. You really could not go wrong with these. Personally I have also taken lots of animals with Sierra Gamekings in several different calibers; they aren't a bonded bullet so they get less respect than the bonded bullets generally do, however. 200 grain Gamekings in a 300 win mag is a very serious combination for big game though.
