Alright fellas, I have an old fixed choke remington 1100 that I used for quite a while but then gave it to my nephew , he used for about 4 or 5 years and then got a new gun. I have since gotten the 1100 back from him but it won't eject lighter shells, nothing under 1 1/4 ounce. Now I have done everything I know to do which includes a complete cleaning and replacing the o ring and it still is not working right. One other thing, the chamber part of the barrel (on the inside) is pitted from rust and I kinda think this is where the problem is but don't know for sure just thought I'd see what everybody else thought.
