I keep no more than about 500 rounds of handgun ammo (per caliber). When I shoot, 250 rounds is the most I will go through. Anymore than that and I tend to tire and lose my fundamentals. That gives me about 250 rounds in reserve and I can keep fresh rounds in rotation. If I want to change a load, I don't have too many rounds laying around. When I get back from a shoot, I throw my 200+ rounds in the tumbler, then load them in about an hour. I do tend to pick up more brass each trip to the range and that helps my supply stay fresh. I toss the bad ones in a 5 gallon bucket that someday will fetch enough $$ when full to buy more powder, bullets, primers, etc. I don't freak out too much about supplies. If I can shoot, I will. If prices stay high, (like they are), I shoot less. I simply cannot afford to make someone rich because prices are inflated. Reloading is very expensive lately. I doubt I could ever have my brass all loaded. But then again, I don't think I would want it that way.
