Hello All - I just was blessed with the opportunity to move from southern CA to northern AZ. I am SO thankful to be here! Anyway, coming from CA you could only really shoot at ranges or in the desert so sparks/fires were not an issue of concern. Now I am able to shoot in the woods but I want to make sure that I don't make any sparks when shooting that could potentially start a fire. I know that bi-metal rounds, such as WOLF are an issue, but when bullets are copper jacketed is that safe or what kind of rounds do I need to be using? Thanks for the help FYI.... planning to shoot paper, metal gongs, etc.
