A common thing I've noticed in this thread is people trying to watch TV while reloading.

I can screw up stuff all by myself. No reason to add the extra distraction.

Many years ago I used to use my Lee Auto-Prime to prime brass while I watched the idiot box. That's about as far as I would take it. I'm super anal about safety when reloading. I still have problems at times. Primers not feeding on my LnL progressive and causing powder to go everywhere is the most common.
