Re: 7mm RUM or 300 RUM
I have the 7 ultra, 300 ultra and the 338 ultra. The most accurate, by far, is the 7mm. The most universal is the 300 and the most fun to shoot is the 338. I have taken animals at several distances with all, and the answer is you can't go wrong with with any of them. I couldn't pick so I ended up getting all three.
