After all of the primer/powder/bullet shortages in the last decade or so, I'll never come up short again.
Like food, I buy and rotate stock and use everything I have.
Once I settle on a load in a rifle, I load as much brass of the chosen brand as I have available with that combination and have supplies on hand to reload 2x or 3x more times.
Fool me once, shame on you. Fool me twice, shame on me.
