When loading, it's inevitable that you will occasionally crush a primer when it doesn't seat right in the primer feed. Some people are not particular about the actual number of rounds they load, so when that happens, they load 99 and forget it. Some people want to load exact numbers of rounds. In that case, they have to open another pack of primers.
I like to fill my ammo boxes... no more... no less, so I long ago forgot about trying to keep even component counts. I just keep the primer feed full and only count my rounds.
There are some things that I could lose sleep over though.
One of those is knowing that there are little bits of explosive laying around my shop that if set off at an inopportune moment, could at best cause me to **** my pants, or at worst cause me to saw my hand off.
