    Thanks Bobster. You are correct. I have the 20" tactical, cylinder bore that came with no choke and no threads to install one. I had it threaded later. These are fine for HD, trap practice and slugs. My issue was I wanted to use it for tactical competition which involves knocking down steel plates. The 20 ga is at a slight disadvantage against the 12 ga, less metal down range. The added concentration that the choke provided has let me knock down anything so far. This is not to say that if I was a better shot, the cylinder bore would not do the same. I have also put RIO #1 buck through both chokes with no problems.
    I use the Trulock extended Precision Hunter (PH), Improved Modified (if there are no slugs in the match) and Improved Cylinder if I have to mix in some slugs. NO SLUGS IN ANYTHING SMALLER THAN CYLINDER OR IMPROVED CYLINDER.
    I keep the IC choke in when not in use just in case I had to use it and grabbed a slug or two.

    What Barrel do you have? Is it threaded? Make sure the threads are correct. I think the factory barrels take Benelli chokes.
