The bullets tested were acquired from an 'exotic ammo' booth at a local gunshow. They appear to be CCI hollowpoints, with the hollowpoint cavity filled with some sort of impact-sensitive explosive that is light blue in color.
All cartridges appeared to initiate upon impact with the gelatin block. This was evidenced by the dark-colored residue in the penetration tracks. Also, a secondary explosion was heard during the normal sonic events of bullet exit/gun cycling, etc, that was not present during the testing of 'normal' .22lr ammunition in the same gun.
Cartridge : .22lr 'Incendiary'
Firearm : Walther P22 with 3.5" barrel length
Block calibration : All depths corrected (From 9.0cm @ 566 ft/sec)
Shot 1 - Impacted at 893 ft/sec, penetrated to 8.3" and was recovered at 0.313" average diameter.
Shot 2 - Impacted at 910 ft/sec, penetrated to 8.9" and was recovered at 0.309" average diameter.
Shot 3 - Impacted at 920 ft/sec, penetrated to 8.5" and was recovered at 0.319" average diameter.
Shot 4 - Impacted at 885 ft/sec, penetrated to 8.6" and was recovered at 0.322" average diameter.
Shot 5 - Impacted at 919 ft/sec, penetrated to 9.0" and was recovered at 0.321" average diameter.
