Shotshells are biodegradable, just like toilet paper.
Its funny sometimes things happen at the most ironic times! As I’m reading this post earlier today, I’m sitting in the oldest deerstand on our property. A stand that in November of 1996 I shot my first,second, and third deer. All on opening morning. Also the last time I or anybody else used a 12 ga for deer. I look down in the leaves and see 2 of my 5 empty shells. I had found 3 and figured those were the three that hit! Anyhow, these shells are now 24 years old. Definitely not breaking down to quickly.
