The velocities on the Hornady boxes are not expansion velocities, they are the velocity range which Hornady loads them to in their various calibers. Many articles about the .32 H&R just parrot Hornady's velocity range, assuming that there is expansion - they are wrong at much under 1000 fps impact velocities. I've searched the internet for actual testing of .32 XTP expansion, below are some of what I've found. It appears that the 85 XTP needs at least 1000 fps impact velocity to offer enough expansion to begin folding the jacket back, and the 100 XTP needs around 1200 fps. Both velocities are safely achievable in strong .32 H&R revolvers (
NOT weak H&Rs!) with at least 3" barrels.

The Black Hills loads use the 85 grain XTP bullet, under 1000 fps expansion is there, but minimal.
