A full size coffee container will hold exactly 600 38 specials loaded with 158 grain LSWC. Just finishing up a 5000 round 38 special reloading project. Starting into a 5000 round 357 magnum reloading project as of right now. The large coffee ground containers were a favorite of my great grandfathers for storing reloaded ammo, when we went through his house recently he has dozens and dozens of them in his reloading room, I'm gonna use em too, makes me feel good to use em just like he did.
