Yep.
Last spring I loaded several hundred rounds of ammo for EACH of five rifles in .17 Fireball, .17 Remington, .204 Ruger, .221 Fireball and .220 Swift for an extensive prairie dog "field test" of a new line of varmint bullets. I got it all done in three afternoons. I couldn't imagine loading that many rounds without having worked out some form of mass manufacturing--and eliminating useless steps.
