I'm a 280AI nut and have never got where you are at and neither of my rifles will come close to those pressures/velocity.
I'd be careful.
I haven't either. I have gotten around 3000 fps, but with some overpressure signs so I backed off. Right now, i can get great groups in the 3s with my rig at 2920 fps average with max load of RE22 through a 29" bbl.
YOu must have a fast, fast, fast barrel, or your chrono is off.
