Reloading Math:Barrels & Buckets

[theblackknight]

Anyone here have a rough estimate for standard 5g buckets and 55gal drums for

How-many-inches-full x what-caliber=how-much-brass?

[rdbse]

Just weigh the buckets. Use a scale to determine how much brass equals a smaller weight (ten cases equal "x" ounces). Do the math and subtract the weight of empty container.

Have you been able to find out a way to figure this out yet?
