Comparison of Difference in Blackening obtained from a Country made Pistol of 7.65mm at different Ranges
International Journal for Research in Applied Science and Engineering Technology
A variety of country made firearms are manufactured in different parts of India. These firearms are designed to fire shotgun, pistol, and revolver as well as rifle cartridges, which are easily available. But there is great difference in manufacturing of standard firearms and country-made firearms. Country-made firearms are made up of locally available materials with no proper or standard measurement. This causes a great hindrance in the estimation of range of firing from GSR distribution
... distribution pattern made on the target surface. The main aim of this study is to show that range of firing cannot be determined by observing the blackening present on the target in case of country made firearms. The present study includes firing of 7.65mm ammunition from 50 country made pistols at three different ranges of 10 cm, 20 cm, and 30 cm. The blackening pattern obtained on the target was measured and compared to know whether it is possible to estimate the firing range by studying the pattern of blackening seen on target surface. Result: After comparing the observation and measurement, it was seen there was significant amount of inconsistency in the values of blackening obtained from different firing ranges. Conclusion: Thus, it was concluded that range of firing cannot be estimated by measuring the amount of blackening obtained on the cloth target in case of country made firearms.
