Cartridge : Handloaded 85gr Hornady XTP Firearm : Kel-Tec P32 Block calibration : All depths corrected (From 11.1cm @ 605 ft/sec) Shot impacted at 852 ft/sec, penetrated to 13.9" and was recovered at 0.358" average diameter. The bullet exited the block at 13.9" and was recovered at ~ 0.1" into polyester bullet catch box. This is to say that the penetration of the tested bullet would not exceed 14.0" in ballistic gelatin. Greater performance can be had by the 71gr and 76gr XTPs.... but you have to make those by lathe or by grinding the base of a 85gr XTP.
