cr500- i'm told by the Australian agents for Remington that, IF they bring Hevi-Shot in- it will be dear - similarly priced to Eley-Hawk 21/2" Bismuth which sells for about AUD65 per box of 25!!

If your English gun is proofed for 21/2" cartridges, IMO, you should use Bismuth. If it's a heavy 23/4" or 3" gun with open chokes (more open than 1/2 choke), you MAY get away with European CIP Steel loads, but remember that American SAAMI pressures are subtantially higher, and Hevi-Shot loaded for the North American market would most likely be incompatible with ANY English Gun.

BTW, in England, it is illegal to use Steel in 21/2" guns.
