I run mine at 2640, was just a load I threw together and it grouped well so used it and haven't bothered doing any further development. Shot a big stag at just over 500, that's the longest shot on game with it, decent nber in the 400 range and most others I the 2-300 with a few up close and personal. All with 162gr, never had to worry about over expansion up close and does well to the 500 mark which is my self imposed limit on game.
My first lot of up sized brass gave me pressure issues and I then found I had an internal donut, a relief cut with neck turner at the neck/shoulder junction prevented that happening in New lot of brass and removed the pressure issue. If you are using sized up brass and getting slightly thicker measurements at the junction it might be worth having a feel inside for donuts
