I load for a few of my buddies, but I made a rule after a few years of doing it. I make the buddy bring in his gun, and his body, and then I make him help me during the process. I really don't like "wasting" my time loading ammo that I can't shoot, so I got them all trained to where I usually sit back and sip on a beer and just supervise anymore.
