Having had a 7-08, 280rem, 280ai a 7mm rem mag and a 28 nosler, I think I’d skip the 7mm mag and go straight to a 38 nosler. I currently have a 280rem a 280ai, a 7mm rem mag and the 28 nosler and there is just not enough difference between the 280’s and the 7mm, especially the 280ai but the 28 nosler is definitely a step up. If I could have just one .284 it would be the 280ai, but if I could only have one 7mm magnum it’s the 28 nosler.
