My .02 is get the 06 as you have better bullet selection and can be used for everything from PDs (55 grain) to Biggest game on the NA Continent.Nothing really against the 300 or 338 I just think they are less versatile and won't be of as much use to you.Oh, I would get the Savage as well. Super accurate and less expensive so you can afford more glass if you are anticipating long shots.
