Area of a circle = Pie (I know you'd like this formula! ) x radius squared ( in inches). times 4. Do that for the outside of the barrel. Now do that for the inside of the barrel and subtract that from the OD number. Now multiply that by .2833. That's how much it weighs. (in pounds
Or just throw it on a scale and weigh it!

You are right, I use a rough guide of .2833#/cu. in. for steel and .097#/cu. in. for aluminum. Some alloys will vary, but not enough to matter (much).
