I've had the same issue with black clouds, over crimped. I even had on box of #2 black clouds that had crimps folded completely into the wad and no shot. The sent me a voucher to replace them, nobody would take it. Kent is good but tends to rust faster than most shells. I tried a box of the Remington Hyper Sonics, don't like them it sheared a magazine retaining plug on one of my guns. Winchester Blindside is OK but too pricey. I do like the blue box or red box of Federals, I have not had an problem with them at all.
