According to Bureau of Ordnance drawing number 440559 for a 16" projectile (H.C.) Mk 16 Mod O dated 28 May 1945 the weight of the bursting charge is (I think as the copy is blurry) 158.57 lbs of Explosive "D" with a density of 1.46. The volume for the bursting charge is 2,670.58 cubic inches.
The projectile body alone is 1,571.50 lbs. Weights of rotating band, base plug, container & nose, adapter, container charge, base fuze with tracer, time fuze, auxiliary detonating fuze and gaskets brings the total weight of the projectile up to 1,900.00 lbs.
I have other BUORD drawings of a few other projectiles as well but the question is not asking me to dig them ALL out (thank goodness).
