Well I cannot get the photo to load but the case has a big bulge at the bottom close to the rim.

I was sorting through some brass I cleaned getting ready to do some reloading and I found this. Looks like a discharge while not in full battery? Way do you guys think.

It's a m&p 9mm, using a storm lake barrel. This is the only bulge over ever seen, probably spent 5000 rounds through it

the storm lake barrel did have an extremely tight chamber( i couldn't use my lead bullets), so I had sent it to storm lake to open the chamber up a little more. I have no idea when this case happened or even if it was mine, just assuming, but I found this in about 2000 cases i had been cleaning.
