Many thanks to Buffalo Bore Ammunition for sponsoring this test.
=========
Cartridge : Buffalo Bore 158gr Soft Lead SWC-HC (Part # 20C)
Firearm : Smith and Wesson 642 (1 7/8" barrel length)
Block calibration : All depths corrected (From 10.6cm @ 611 ft/sec)
Shot 1 - Impacted at 883 ft/sec, penetrated to 14.5" and was recovered at 0.399" average diameter. Bullet experienced moderate fragmentation, with the individual fragments penetrating deeply enough to be potentially effective.
Shot 2 - Impacted at 899 ft/sec, penetrated to 14.5" and was recovered at 0.429" average diameter. Bullet experienced moderate fragmentation, with the individual fragments penetrating deeply enough to be potentially effective.
Shot 3 - Impacted at 925 ft/sec, penetrated to 14.5" and was recovered at 0.389" average diameter. Bullet experienced moderate fragmentation, with the individual fragments penetrating deeply enough to be potentially effective.
Shot 4 - Impacted at 946 ft/sec, penetrated to 14.5" and was recovered at 0.400" average diameter. Bullet experienced moderate fragmentation, with the individual fragments penetrating deeply enough to be potentially effective.
Shot 5 - Impacted at 878 ft/sec, penetrated to 14.5" and was recovered at 0.437" average diameter. Bullet experienced moderate fragmentation, with the individual fragments penetrating deeply enough to be potentially effective.
Please note that the actual bullet cores (and a few large jacket segments) penetrated out of the back of the block and no more than 1" into polyester fabric placed behind the block. The pictures depict a bullet/fragments that penetrated 16.1" (the entire length of the block). Because the block did not calibrate as a 'perfect' block, a correction formula was applied to the bullet core only. The shape of the core was cylindrical, so that drag coefficient was used (from the book Bullet Penetration). Penetration in an ideal block should be slightly deeper than 14.5" for all bullets tested.
