I noticed the dull black burnt look on one side of these shells today. I shot about 6 rounds and every one turned out like this. They are 12ga Winchester Longbeard 3" #6 shot. I've had the same 870 for almost 30 years and this is the first time I've ever noticed spent rounds looking like this. The one on the left has the same burnt spot as the one on the right. I just turned it to show the difference.
All mine look like that
the shells pattern fine at 40 yards but I was curious about the burnt side.
I'm guessing it's because they are roll crimped instead of folded in. The roll crimp isn't as long and lets some gases leak into the chamber.

what gun you shooting them out of Tom?
Rem 870 and a Mossberg 5500MKII
The old white hevis I used to shoot didn't do this and they were roll crimped. Any handloaders see similar with TSS loads? I'm curious, love the patterns they put out but a singed hull would raise an eyebrow.

They do it in my Mossberg 835 also
Every one I have shot out of my Mossberg 500 looks like that, I just don't reload em

I've noticed that on mine as well!! As was mentioned above, could be the rolled crimp, or it could be the resin inside burning off.

I have not. I have several spent hulls with roll crimps and none have a burnt look. Will add a photo when I can figure out why Tapatalk is acting stupid.

X2
the XX shells do it in my 12ga guns
They all do that in my Mossberg 500. Never had a problem
mine look the same
Normal for the longbeard shells? Yes .
Others? No
They do the same in both by BPS as well as my Cynergy.
thanks for the replies. it seems to be common deal with no major issues so I'll just keep on shooting'em.
They come out of my sbe2 looking like that. Has anyone left them loaded or forgot to unload them from a sbe2 and have the end where the crimp is flare out???

That's comforting.
I leave my gun loaded in my truck when I'm hunting on my lease. If I leave it loaded all week. The two shells in the tube will be mashed and flared out where the crimp is. I think the 3.5's compress the spring so much that it causes the deformation.
We posted about this last year or so but also the overshot card coming apart and making a benelli jam up.
