There's a forgotten era/aspect of factory ammo. I've been reloading since the mid 70s'. Super Vel started the lightweight bullet/high velocity era. They put light bullets in 38sp & 357m and 180jhp in 44m. Soon the other major manufacturers started doing it too. As bullet expansion technology got better,the need/want slowly went away. The current crop of wickedly expanding bullets far surpasses what existed before.
