The Lyle "Life Saving" gun. This one was at the Casper Cannon Shoot. It shot tennis balls. According to the information I have access to, the Lyle Gun was of 2 1/2" (2 pounder) bore, capable of firing a line-carrying projectile of 18 pounds with a line attached, a distance of 1050 feet to within 50 feet to the left or right of the point of aim. With the whip line attached, additional lines could be hauled out to a stranded vessel for rigging of a breeches buoy. (?)
Gun weighed 163 pounds and later ones were made of 65,000 psi or better, steel or bronze. Recoil, since the guns weighed about nine (9) times the weight of the projectile, was vicious but they did get lines out to the stranded ships or from ship to shore or even ship to ship. Blaster
