[edit] UK 15 inch 42 cal naval gun - supercharging

I understand from various sources, including the book "The Big Gun(s) (?)" that the RN's 15" 42 cal guns could be supercharged, and that there were various levels of supercharge used (some of which may have reduced barrel life to 3 rounds only). Does anyone know:

• the weight/mass of supercharge that could be added to the normal charge,
• the weight/mass of supercharge that was allowed for in VANGUARD and the ROYAL SOVERIGN Class battlewaggons (?these could be different),
• the weight/mass of supercharge that was used in army weapons (I think this was much higher), and
• the resulting muzzle velocity/muzzle energy in each (or any) case?
• the range possible in each (or any) case?
• the effect of supercharging on the 6CR shells (1938lbs(?)) vide the 4CR shells (1920lbs(?))ditto?

See here for a good starting point. I think you'd have to get your hands on a copy of Campbell's "Naval Weapons" for a definitive answer. Emoscopes ^Talk 12:29, 29 April 2007 (UTC)
