title: An experimental study of powder tattooing of the skin.
abstract: Test firings were conducted on specially prepared live rabbits to determine the approximate maximum ranges at which powder tattooing occurs for different forms of gunpowder. For .38 caliber, powder tattooing from cartridges loaded with flake powder disappears at a range of 18 to 24 in. (0.4 to 0.6 m). Powder tattooing with flattened ball powder extends to 36 in. (0.9 m), while that due to ball powder extends to 48 in. (1.2m) of range. In .22 caliber, powder tattooing was observed out to 24 in. (0.6 m) with flake powder and 18 in. (0.4 m) with flattened ball. Attempts to reproduce the animal powder tattoo patterns on paper revealed that the paper patterns are consistent with skin tattoo patterns only up to 18 in (0.4 m) of range.
