I have moved with guns about a dozen times, a handgun stays loaded near me (welcome to the south, we have gun freedom here.)
the rest were heavily oiled and wrapped in many Layers of paper for protection.
One move I did not know what conditions they were going to be stored in for how long so I covered them thickly inside and out in Vaseline, works like a lighter duty version of cosmoline, sealing out oxygen and moisture. again wrapped thickly in paper then in trash bags, then into a large wooden chest with loose fill, fortunately I was able to get into dry storage before humidity made troubles.
It is a chore to take them out of petroleum jelly. But everything was protected.
I would never trust movers with firearms, although I am sure there are some who are trustworthy, it is a low status job witch is left to those who for many reasons cannot get better work. For many that reason is substance abuse, you gun collection easily converts into thier expensive substance of need.
