Hi all, I'm new to the shooting scene, and up to date I'm only on the clays, iv bought the berretta a300 which I really like, the gun came with one choke, 1/2 I think, thing that I'm thinking about is do I need more chokes?. Iv bought the gun for on the shore, and was wondering if I need a tighter choke? Can you use a tighter choke with steel? And if so any recommendation on a choke? Many thanks in advance
