I received a 11-87 as a gift and it only came with the one choke. I thought that was kind of odd but maybe not as I am fairly new to the hunting world. It is a modified choke. My question is about shooting steel shot out of it. Is it ok? How can I find out if it is ok? From a little research I have found that it is safe but may harm the gun over time. This was my first gun so I would really like to have it forever.
