Back in 1856, at a small pre civil war battle, between Missouri border ruffians and Kansas abolitionists, a 6 pounder was used to settle the dispute. The 6 pounder was fired at a range of about 200 yards into a log blacksmith shop. I am pretty sure, I have located the shop area. Survivors from the blacksmith shop, said the cannon balls were passing right through the logs. I have permission from the property owner to search for the cannon balls. Anyone have any idea about how far beyond the shop I should start my metal detector search? My avatar is a picture of the 6 pounder, and probably part of the crew that did the shooting. Thanks Boomer
