Description: | Lead Musket Ball. Cast shot with a circumferential flattened belt due to 'set up', which is the effect of the immense forces generated by the propellant charge in the first milliseconds of firing on an unwrapped lead projectile, whose inertia before it begins to travel up the barrel combines with the explosive force behind it to distort the shot by pressing its sides against the inside of the barrel. The mass of the ball, at over one averdepois ounce, is apt to use with a muzzle loading firearm of military specification. Suggested date: Post-Medieval, 1600-1800.Length: 17.2mm, Diameter: 16.9mm, Weight: 30.26gms.mm, Diameter: 16.9mm, Weight: 30.26gms.
