No.
As an extreme example of vehicle movement, I'll mention a mode of transportation I once had. I was a TC on an M48A3 tank in Vietnam. The crew and I all had issued M1911A1 pistols and ball ammo. Travel over severe terrain, firing the main gun, vibration, etc. had no effect whatsoever on ammunition, magazines, or reliability of our pistols. In civilian life, I spent some decades as a police officer. Again, vehicle movement had no effect whatsoever on ammunition in magazines or pistol reliability....ymmv
