Here's the Hornady online catalog...check out page 21. It lists velocity ranges for XTP bullets.
The chart isn't exact and cuts off at 800 fps, but does give a generally range. Looks like:
155 gr XTP - 900 to 1300 fps
180 gr XTP - 800 to 1500 fps
200 gr XTP - 800 to 1200 fps
Maybe a little more, maybe a little less, hard to say based on the chart. Looks like Hornady designed their XTP line to expand over a wide range of velocities, but if you're really pushing the 10mm really hard you might be at the top of the range.
