This paper dealt with the power and risk evaluation of pipe type homemade firearms using black powder and steel ball, based on actual incident case that occurred in Republic of Korea(2016 Opeasan shooting incident). As a result of experiment, although pipe type firearms has a very simple and basic structure, it showed threatening power. It was confirmed that the main effect on the power of a pipe type firearms is the amount of black powder charged. The pipe type homemade firearms in the experiment used a 6.7~11.5 ㎜ steel ball as projectile, and it is judged to be powerful enough to kill ordinary people even if only 1.5~2.5 g black powder is used. In addition, depending on the amount of black powder, it not only has the possible hunting power of a very large animals(227~998 ㎏), but also has kinetic energy that is more 1.5~2.5 ratio higher than the industrial pistols. According to the result of experiment, the power of homemade firearms is variable and difficult to predict, so if similar case occurs, it is considered that the same response as an actual firearms incident should be shown. In addition, it is considered that related organization have to continuously maintain preparedness for this type of shooting terror or incident.
