Well these guys certainly already answered your question but I can add one other option, and that is the Nosler S.H.O.T.S.
I use the 300 grain in mine and it performs very well. Basically just a standard jacketed bullet for a fraction of the cost of Partitions.
The bucks I have taken didn't notice that they were not premium rounds...
The bonus is they are supposed to be balistically identical to the Partition and shoot exactly the same so you can switch between them if needed.
