Steel shot tubes to use?

[lemon hart]

Have decided to get back into migratory waterfoul shooting and was wondering what choke tubes I need to use with 3 inch steel shot shells. I know that full choke is a no no especially in my OU. What tubes would you suggest so as not to damage my Beretta Silver Pigieon III gun. Thanks for any advice.

Try both Imp. Cyl. & Modified ... see which patterns best at the average yardage you might shoot. Beretta recommends nothing "tighter" that Modified, and the Mobil Chokes suitable for steel shot have "SP" marked on them.
