I realize my reply was a little harsh. Let me explain myself for the factory IC. The blackcloud load uses a flight control wad. The wad is designed to hold the shot column in the wad to longer distances then normal wads. The last thing you want to do with this stuff is shoot birds with it under 20 or 25 yards if you plan on eating them. Past that when the pattern starts to open up its good stuff other then the gimmick pellets in the load.
If you are looking for tube to pattern the xpert or other shot types with do yourself a favor and save the money go with Carlson's if your factory tubes don't do what you want. They are much cheaper and you can send them back until you find the tube that patterns the way you want it to
