A quick internet search shows claims of 1500 EFC for the US/German gun and 1200 for the Russian gun. The few hundred rounds claim seems to be based on open source information about the 120mm rifled gun used in the Arjun/Chieftan (Challenger?) posted by DRDO which states a life of 500 EFC.
Thank you Zraver, very concise and useful!
