As long as you stockpiled regular jacketed or plated (pistol) projectiles, you could forgo the lead dipper, pot. and sizing die/lube. Especially for 5.56/.223, since FMJ projectiles are still relatively cheap. Plus, 5.56/.223 doesn't use as much powder as the bigger rounds like 7.62 NATO, so the same pound of powder would go a good bit farther.
