Hornady used to have a poster that listed the velocity windows of each XTP bullet they offered. I cannot find mine for the life of me..

IIRC, the .429 240gr XTP had a velocity threshold of around 900fps for expansion to occur. At lower velocities the XTP will expand to at least the length/depth of the hollowpoint skives, or notches.
