My thoughts are the 280 AI and 7 Saum are very close to each other and basically neck and neck in the field on actual game with the 6.5 PRC./ I think the 300 WSM is the only real step up in performance of the ones listed. Yes, I know the 7s have more energy etc than the prc, but in the field they are all really close when using the same make bullets. The 300 WSM is a decent step up in bullet diameter and weight at the same basic velocities as the others.
If you are open to other suggestions, the fast 33s like 338 RUM, 340 Weatherby, 338 Lapua etc, are pretty noticeable when they smack an elk.
