The 6.5x55 140 velocity will have a 140 Partion working picture perfect.
I don't know about switching between Partions and regular bullets for load developemnt.Speers are supposed to be close,but they didn't work for me the couple of times I tried . I'm guessing here,but the Partions different construction may mean,separate ($) developemnt.
