When I go to the range I only load the gun I am shooting, one gun at a time, I do not pre-load guns or mags at home before I leave the house. When I finish shooting one gun I clear it, put it back into it's case and secure the ammo before I pull out the next gun and ammo.

If I take a friend to someplace like Pawnee I use a loading table for loading and unloading guns and make sure everyone is on the same page for safety. Once the bullet leaves the barrel it ain't coming back (I hope).
