I would've recommended Remington's version of the tried and true LSWCHP, but anecdotal evidence from around the web suggests the new HTP version uses a harder alloyed bullet at reduced velocities. In essence, it now suffers the same problems as Winchester's version when fired fom short barrels.

Also, according to Speer's own data, their GDSB load actually fails the FBI bare gel test, albeit by a small margin. According to their LE poster, it penetrates about 11" or so.

If memory serves correctly, the FBI protocol also mandates 1.5x expansion. It's not just about penetration and any modicum of expansion.
