Thanks guys. I am going to try a couple different things here before buying a new choke.
I bought a box of Federal 1 3/4 oz of #6's in the 3 inch, and also I found a Winchester load of 2 oz of #4's. I will check with these two and see how they do. If I can get closer to 100 with either one, then I will see. If I am still a ways off, then I will got with a tighter choke.
Thanks again,
Marcial
