To be honest ED I don't know whether oiled rounds were used or not; in fact I was always of the opinion that they (Proof House) used an "over loaded" round.(Can anybody else comment on that?)

Regarding CIP as a measurment, I doubt if it was in use (UKicon) during the period of conversions which was from circa 1969 and the last conversions I can find were around 1986.
