Dont store ammo that you just reloaded on top of you safe where you can knock it off the safe and all the shells come flying out and the plastic box breaks. This really wouldn't have been a big deal except for the fact that I loaded five shell @ 49 grains, then five shells @ 50 grains, then five shells @ 51 grains, then five shells @ 52 grains, then five shells @ 52.5 grains, and finally five shells @ 53 grains. Man I was so pissed off that I did that. What to do. So I went back down to the garage and started to measure them on the scale and sort the out by weight. What did I learn. First, dont store ammo on a high shelf where it can fall off of. Second, mark each shell with a sharpie with the weight on it.
