With Partitions I get 2700 with 59.0 grains from the 24" barrel.
Many years ago used to load up to 61 grains of H4831 (probably the made-in-Scotland version, the transition powder between the mil-surp and present Australian-made H4831 Extreme) in a 22" barreled Ruger 77 to get 2700. But that was in Winchester cases. Remingtons were heavier and only required 59 grains.
The Hodgdon top charge for 200's these days is 59.0 with AccuBonds, but that's at the long-time SAAMI maximum average pressure, which isn't very warm. Am sure I could add another grain, or maybe two, of H4831SC to the load for my NULA, but so far haven't bothered. 60 grains would get around 2750 and 61 2800.
Actually 2800 should be be reachable at 65,000 PSI in a 24" barrel with several modern powders.
