I've had this problem with my various Beretta o/u's and a couple of my Spanish sxs's. I have experienced it with all kinds of "economy" ammo. I disassembled a couple of Estate shells the other day that were all bent out of shape, straight from the box. I had Remington's on which the metal heads pulled away leaving the rest of the hull in the chambers,
Remmington made that good, but I didn't have the lot #, etc for the Estate shell. With 20 bure I just quit buying them for use in my 686. My learning, spend a little more and have fewer issues. I also usually run my hands over all of the shells when drop them into my ammo pouch.
