I am currently building a pair of .375 double rifles which will be heading to the States once complete, I need somewhere to regulate them prior to this. I will need to shoot them out to 200 yards and the closer the range is to London the better. Does anyone know of anywhere that may be able to accomodate me on a weekday for an hour or two? I was wondering if anyone has any contacts on military ranges where I could go? Obviously most civvy ranges will not allow .375's and don't take kindly to brazing equipment being used on the firing point. I have a MOD 90 so access to military land should not be an issue. I will also furnish the range staff accordingly. Any help in this matter is much appreciated.
