I remember my first cartridge, it was an Eley Magnum .410 16 or 18 gram. Lovely cartridge for a 4 year old! I know I was hitting crows (with the help of my Grandad or Uncle Del) within a few shots and im still hooked 20 years on, and lucky enough to still have my Grandad to go out with on pigeon and our little syndicate that we are half guns on.
Fire one cartridge and you are interested, have the passion of 2 guys you look up to and fire that one cartridge you are hooked for life!
