I know some people who have so many firearms they literally cannot remember them all. This particular person, moved from Alabama to Texas and she and her husband were forced to rent a totally separate U-haul trailer to transport all their ammunition. She said the ammo was “stacked up to the doors.”
In relocating my household over a thousand miles from the Midwest to a happier place out west, I had minimal problems until crossing a set of nearby railroad tracks within a mile and a half from my destination, I broke a rear axle on my one-ton pickup, loaded down with a goodly supply of ammo.
That's really slowed down my plans to move the rest of it out. But I'll make do.
