I don't want to take this off topic, but I have to wonder how someone shows up at a match with a backwards primer. I just started re-loading, and every round I load gets looked at several times. If it's going to a match, it gets measured for length and gauged. If not, it still goes in the ammo box primer side up, and gets a close look to make sure every primer is seated properly. I'm only loading about 500 rounds a week. Maybe if you are doing several thousand a week you don't have time, but for a match why wouldn't you?
