I recently picked up a Browning BPS 10 gauge and have questions about what I'm seeing at the rim of the hulls. There are cracks or deformation on the rims of some hulls of newly fired ammo. The ammo is Estate brand 1 5/8 oz. 2 shot steel, max dram eq. 1375 FPS. The other picture is a once fired Federal hull factory buckshot load.
I've noticed more than half of the hull rims don't easily slide into the wad station of my 600 Jr as well (new once fired Federal rims) but new ammo rims slide in normally. I didn't notice the cracks till I reloaded a few rounds. The pic of the loaded shell is a once fired hull that WAS going to be fired a second time.

Im wondering what I got here. Must be an issue with the action?
