I have no clue, John, no chrono. It's plenty splattery and very accurate, which is what I was after. I would guess 3200 based on the difference in recoil and "bang." The same powder charge (10.7) also works fine under the little blunt 35VMs, about the same group size. POI does change between loads, so I shoot through batches then rezero.
I bet Seafire can tell you the speed -- in fact, I think he did a full velocity workup for the Fireball in one of his data dumps. I know for sure he did one for 223 and BD which affirmed the point at which speed gains fall off, about where I shoot my 223 blue dots.
