I shoot Winchester Dryloks. Not cheap steel, but not premium either. Both my Browning Gold 10 ga. and my Browning Maxus 12 ga. like the stuff. I hand load Heavy Weight 13(generic Hevi-Shot), for both 10 ga. and 12 ga. I use the HW-13 loads for cripples, on the water, or if shooting stout cross winds, which shred steel shot patterns. HW-13 make a big difference in wind, and also helps if the birds are really spooky, reach out another 10 yards. As far as Black Cloud, or Blindside, I concur...gimmicks.
