Goal of the Since no references testing the possible effects of the presence of lime were found, this study was undertaken to test any potential interference from limeon the examinations conducted for nuzzle-to-target distance determinations. Due to the basic nature of lime, the results of the studies may also be useful in predicting whether interference might be expected due to the presence of other chemically basic substances during muzzle to-target distance determination examinations. Materials and Methods Before line could be tested for potential interference with chemical testing commonly associated with distance determinations, a firearm, appropriate ammunition, white cotton cloth for patterning, materials and chemicals necessary for the Modified G Test and the Sodium Rhodizonate test and powdered lime were collected Magnum Sufficient amounts of 380 ACP. 9mm Luger, and 357 ammunition were available. One box of ammunition was selected for each caliber. One firearm of each caliber was
