Poly choke

I have a old beat up sears and roebuck Ted Williams mod.75 semi 20guage. It has a poly choke and was wondering if you can shoot steel out of her. I shoot a 12 guage but my little brother wants to go duck hunting with me and was just wanting to make sure its safe for him. I've googled with zero results.

No.....you will ruin it.

Thanks now I wonder if I could take it off. I have 2 old sears 20s ones a pump and ones a semi but I have no idea on polys

CHeck to see if Bismuth or HeviShot woulf be okay in it if your not going to shoot a whole lot $$$

You need t make sure the barrel is chrome lined. If it is real old, it will not be and anything steel will ruin it.

Thanks for the help guys think I'm gonna buy a stoger (spelled right?)off a Buddy thanks!
