Under 500, about any will work. Your partitions certainly will. Accubonds, barnes, hammer, swift 210 scirocco, 225 a frame, 250 a frame.
I use the 210 swift through my 338 rum for elk and moose, and everything else. If you drop to a 210 class, you'll pick up launch velocity and the tougher bonded bullets can handle the velocity increase. In my experience, bullet construction matters more than actual weight.
I really like the Swift A-Frame. They are built like the Nosler Partition, but they are a bonded bullet whereas the Partition is not.
