Steel shot is considered safer than lead shot primarily because it is lighter, which reduces its velocity, and it is nontoxic. Using steel shot minimizes the potential for soil and water contamination that can occur with lead shot, which poses a risk to wildlife and environmental health. This reduced weight and the properties of steel allow for a decrease in the environmental impact while still providing adequate performance for hunting.

In contrast, the other aspects of shot characteristics, such as accuracy or cost, are not the primary factors for safety. While some hunters may perceive costs or availability as influencing their choices, safety remains a top priority, making the reduced toxicity of steel shot a significant factor in its preference over lead.
