57 grains should get around 2500.
We did confirm, though, that velocity is the best predictor of pressure for the average handloader.
I would love to see a article written around these lines. Showing variations that can & do occur in manuals vs what individual rifles are like in the real world.
For my part, I load 250 grain bullets in my 35 whelens and adujust the charge until I get to or around 2500 fps. It has worked great in both of my custom mauser & my bone stock Remington 7600. My load using 250 grain speers is 57 grains RL 15 in my mauser. Never tried working up a load for the Hot Cors in my Remington yet. After I go through all of my Hornady 250 grain round nose bullets I suspect I will.
