I've often wondered the same thing. I searched Privi Partisan website and came up empty. I'd personally follow data for the bullet weight itself and work up as usual observing pressure signs.
I developed a load with the 200gr Nosler earlier this year with Varget and IMR 4350. Both powders were super accurate but the data in the Nosler manual suggests the 4350 to exceed 2600 and I'm here to tell you it's impossible with that powder. I got more velocity with the Varget. In my rifle I got an avg velocity of 2566fps. The 4350 only netted 2438fps. Both loads were book max charge.
