I am going to be taking a level 2 defense class and a case of ammo for it. I was wondering what is the cheapest 9mm that is reliable. I was thinking probably 115 gr fmjs since I will only be shooting targets, but I don't want some crappy ammo that is going to be misfiring on me during the class. I found some stuff at www.cheaperthandirt.com but I was wondering which brands of the cheap stuff are ok, and which to stay away from.
