I've owned several 300s and still have a few, but personally can't find where they have performed any better than smaller carts such as the 270WSM, 270Wby, 7RM, or like carts. I'd like to say they do, but with modern bullets, I just don't see an advantage.

For example, would you really feel undergunned toting a 7RM with 160TSX vs the 300 with 180TSX?
