I wanted to find out if the Firebird 50 exploding targets would still function if they were left outside. I also wanted to know if their shelf life would affect their performance. So, I stuck one outside and left it there through two snow storms and sub zero temps all the way to around 55 degrees. I've had an opened package of them for many months so, I was able to test the life span a little as well. They've been stored in a non-insulated garage for most of the time that I've had them.
