Can I please be difficult and throw a spanner into the works? Your 28 Nosler has some serious legs, so why go with a second rifle achieving the same goal? If I may, take something that serves a different purpose, but can be used as a back up… My suggestion would be a .338 WM, assuming you won't ever be shooting DG. I know that wasn't your question, but I did say I was going to be difficult. Maybe just give it some thought? Always nice knowing that you have some extra insurance when that kudu/eland bull isn't standing at the greatest angle.
