I USE TO reload for others LOOOOOONG ago but no longer for all the reasons already stated. Besides my sons, will loan firearms to three people only. Had a pretty good friend take strong offence of my changing my yes to a no on loaning him any of my rifles for a coyote hunt when I found out it was going to be done by a large group or groups of hunters driving hedgerows. I'm not kidding when I say he was visibly upset and insulted. I figured our friendship had suffered irreparable damage, but I shuddered when thinking of the potential for tragedy when people are shooting at a fast moving coyotes with high powered rifles in a group hunting and driving situation.
Found out soon after the hunt one guy accidentally wounded another while shooting at a running yote with a shotgun that the single "O" buck shot ricochet off of the ground (guessing most likely a rock) and wounded one of the other hunters. Not a life threating wound but required surgery none the less.
These days you simply can not risk the liability of loaning firearms unless absolutely certain you trust the person and then I wouldn't loan the rifle with my reloads to anyone other than my sons who only hunt with me.
