In my experience you can reload .223 55gr soft point ammo for about the same price as surplus/Wolf 5.56 FMJ. Essentially you're loading hunting ammo for the same price. But that doesn't include the cost of your time, only compontents.
I store my powder in one of those real cheap sheetmetal roll around tool boxes like you find at Walmart. And then I store the primers in the lift off tool box that sits on top. Never store them together. Bad juju.
But I haven't done any reloading in about 5/6 years. I do need to build some more -06 for the Garand and .303 Brit though.
