The only way to get it to met the FBI numbers is to push it that hard. For non +p the best out there is safestop (really expensive, single source) and regular wadcutters (not semi wadcutters). Both those rounds just go in. No expansion, but they penetrate deep enough, and both have relatively flat points, so they crush and tear through tissue rather than parting it and pushing it aside, making the most out of a .38 cal hole. Hollow points open up, making a bigger than .38 cal hole, and some fragment, making multiple wound channels, but almost all lose penetration deapth doing this. No free lunch. The 135 opens up and penetrates, but at a price.
