I had heard that 9mm doesn't suffer as bad as other popular calibers (ie 40 and 45) so never really worried about it. Now I'm joined a new range by my house which makes me unload before coming into the facility I seem to be loading/unloading more often than I want. I started to mark each round with a black mark and once it has two I fire the round. Now should I continue this practice or am I too worried about it? I would rather not use this ammo as it isn't just WWB 9mm rounds. Yes I do try to put some of the hornady down range at times but the cost just doesn't make it efficient for me to shoot all the time.
