Focusing solely on what I would call his thesis statement, “Therefore, the objective of this study is to describe Idaho hunters (a) lead-free ammunition use, (b) opinions on lead-free ammunition, (c) and personal and social dynamics of lead-free ammunition choice.”
He’s simply gathering the data to understand how Idahoans feel about the use of non-lead ammunition and try to understand the motivations that might cause the sample to voluntarily transition to lead free, or if they even might do that. Based on the survey responses, it seems to me like there was a pretty cut and dry answer that most Idahoans are opposed to it.
