I found this metal detecting on my property. I am not sure but I wonder if it is an artillery shell. It is 10 3/4 inches long and 3 inches across the base. It is hollow. It weighs about 9.8 lbs. It looks like a fuse could be fitted on the end.
Thanks for your input....I do not think it is old iron plumbing pipe.....it is hollow on the inside and there is only one opening......water could not flow through it.
