What do 1000 empty 223 cases look like? Will 1000 fit in a empty 1 gallon paint can? What is a good way to estimate a thousand cases? I guess I could weigh them, I have a US Postal scale, But I don't know what 1000 weigh? I have a big habit forming bag of RMR 69 grain bullets and am digging through all my sorted brass and It looks like I may have enough WCC cases to load them all in like head stamped cases.
