I've put a truck load of steel through my full chokes, back when the "Duck Commander" first started making hunting videos he swore by a full choke with steel shot through his Browning Golds. I have no problem replacing a choke ever season or every other season. The price of the choke is nothing compared to the total cost of steel shot put through it per season. Same point the Duck Commander made and he is definitely a guy in the know how when it comes to ducks, steel shot and full chokes.
