When putting that many rounds through a firearm, would one use something beyond a typical speedloader for the magazine? I would think loading that many rounds would be rather a chore. Actually, even just having to change magazines many thousands of times would get annoying. I wonder if there are any automated machines to handle that sort of thing?
These “tests” are conducted over a number of years while keeping track of the rounds fired, so they do not use any exotic loading equipment.
I have heard of people using multiple volunteers to load magazines.
they had a friend who loaded a stack of mags for them. Also, if you have a mag loader, which is a simple plastic and metal affair, its easy to load em.
