Lance, Nobody has consumed raw cotton to get the nutrient value from it that we know of, so we would not consider it food. Anyway thanks again for that picture; looks like an 8" Columbiad battery perhaps with an iron, seacoast, center-pintle, barbette, carriage upside down from the looks of it. Looks like the cotton armor was two or three bales thick; maybe that's enough. We will eventually find out!
Oh, the latest on our wrought iron trials is that we will buy enough to do a close range, side by side, comparison with structural steel which we picked up today at the scrap yard, about 200 pounds of 4" X 3/8" angle iron. Each target will be 16 sq. in., (4" X 4") and will be shot at close range, about 30 yards, just to compare the relative resistance of each material at 90 deg. and at a 35 deg. slope. We will use the carefully measured results to develop structural steel targets of a resistance to penetration like the wrought iron target displayed, for longer ranges at an acceptable cost level. No matter how we looked at the wrought iron cost, we just could not afford the almost $800.00 that two 12" X12" X 1.333" thk. targets would have cost including the whopping shipping charge.
So it goes,
Mike and Tracy
