I asked the gate sentries - a few years ago now - if it would be possible for me to use my semi-auto CO2 pistols (Mauser Broomhandle and Walther P-38) down there, and was told the land was actually administered by someone up in County Hall, Dorchester. In addition, I now have a beautiful BSA .22 Stutzen Luftgewehr, which I would also like to be able to shoot somewhere, before I die (am now 80 !!)
