Abstract

The purpose of this experiment was to examine the effect of changing the type of action or the barrel length on the power of a shotgun. To do this the researcher fired three different types of shotguns including a long barrel manual action shotgun, a short barrel manual shotgun, and a short barrel semi-automatic shotgun were fired at a paper target made from ⅓ of a pack of paper. The number of pages of paper the shotgun pellets broke was then recorded. This step was repeated three times for every gun and then an average number of pages were determined for each gun and compared to each other. The average number of pages broken by each shotgun are as follows: the long barrel manual shotgun broke 84.67 pages, the short barrel manual shotgun broke 96.67 pages, and the semi-automatic shotgun broke 79 pages, This means that the shotgun that had the most power was the short barreled manual shotgun, followed by the long barreled manual shotgun, and then the short barreled semi-automatic shotgun. In the end, the results ended up being that a short barrel manual shotgun produces the most power. This does not support the the hypothesis that the long barrel manual shotgun would produce the most power. Instead the research suggests that a short barreled manual shotgun is able to produce more power when the pellets impact the target than any other type of gun tested in this experiment.
