I also use a BSS occasionally. Came with 26 inch barrels and both modified choke in each tube. I use 3" BB shells and no issue. However I find the BSS a clunky gun and unbalanced. My go to gun is an older Browning Citori Lighting with a straight grip. It also has 26" barrels with fixed chokes so I had to get the full choke opened to modified. I did put a mercury recoil reducer in the butt. I've been using for about 20 years and have shot well over 10,000 shells in it almost all 3" BB. Seems to me I also glass bed the butt stock when I first got it.
