Environmental Risks Arising from Changes in Ammunition Materials Copyright © 2013 – Cylenchar Limited Dr Peter J Hurley – Cylenchar Limited UK Does Steel Shot Reduce Environmental Risk? Having considered the nature of the hazard from our potential contaminant, let’s consider the wider issue of application to our range with regard to risk. There have been several studies of the behaviour of lead in ranges. Worldwide data suggests that on mature ranges legacy lead in surface soils can reach levels of 10 gram per Kg. Early studies had concluded that lead shot could survive in the soil conditions for 10,000 years and be largely retained on-site. However, experience tells me that at such levels of lead unless the surface is permeable and subsurface geology is clay rich, lead migration problems are likely to occur. Steel has been widely promulgated as a ‘non-toxic’ alternative to lead. And in some cases, local regulators have, perhaps naively, insisted that ranges cease firing lead altogether. I am not a shooter. I’m an environmentalist and a scientist. I fully believe that lead is harmful and that lead shot poses a significant risk to waterfowl, but I have grave reservations of the universality of the switch to steel and other lead alternatives in all shooting applications. Let’s take a closer look
at the impact of shooting steel, and in particular at shooting steel over
lead. Illustrated is a shooting range situated in Florida. The range is circa
50 years old and unfortunately sited adjacent a wetland wildfowl reserve. The
local regulator has imposed a
