The rifle over the fireplace appeared to be a falling block action which was invented in the 1830's so it could not have been used in the 1700's.
Boyd said the lead balls near the fireplace were Minnie balls used in muzzle loaders and were 16 to the pound. Minnie balls look like bullets not round balls. 16 to the pound indicates shotgun gauges. 16 to the pound means 16 gauge. Shotguns are designated in gauges not calibers like in rifles and pistols.
