I use 140gr Nosler Partition and have found that they are great in the 7mag. I also like the Swift 140gr A-Frame bullets or the Hornady 139gr Inter-Bond bullets.
I have a lot of load data I have worked up over my chronograph. PM me if you want more details on loads.
A 30cal will reach out and touch them. A 50cal will kick their butt.
