Hello,
Peashooter will be able to give you the info you require. I would have offered to do them for you but again distance is a problem as also is sending any sort of ammo via Royal Mail and most couriers. Had you thought of joining a shooting club? You would find a wealth of help there, and would also of course be able to enjoy the pleasures of shooting. I can highly reccomend the sport, even after 47 years of doing it myself, I still enjoy every meeting. I can still shoot although I am now a wheelchair user.
Best regards,
Guy.
(Richard, I just love that 2 bore, have you fired it. Did you eventually get the belt?)
All best,
Guy.
