Fiochi 32g 6s .... I have always used this load for all my shooting whether it be rabbits, squirrels, pigeon , crow , pheasant ,duck . I remember the good old days when I used to shoot a lot of rabbits with the shotty over my terriers using Baikal Record , christ they were hard hitting. Another good cartridge back then was Sellier and Bellot I'm sure you will remember them ?
