John and I concur. This has clearly caused a stir of interest and interesting information.
One thing i have observed from meetings with US owners of British guns, especially those who load their own shells, is a bit of over reversal of the old 'magnumitis' that is well known. It is that many feel that British vintage guns need to be loaded with very light, slow and ultra low-pressure shells.
Seeing what is commonly used in the UK in our classic guns might be a useful indicator of what they are made to withstand. any 2 1/2" shell sold in the UK will be safe to use in a gun proofed for 2 1/2" shells.
Some are more civilised than others, but a very wide range of suitable ammunition is available for this 'standard' British game gun chambering.
