I started reloading 30 Carbine today but had to stop due to quickly noticing a problem with my brass. All of it is bulged on one side near the case head, enough so I can feel it with my finger. This is present in both "raw" and resized/expanded brass. It still meets SAAMI specs for the dimensions of the case but it's a bit out of round.



It's a bit hard to see but there is daylight on the on the left hand side due to the bulge. I loaded a couple inert rounds that are just an unprimed case and a round and it chambers, goes fully into battery, and feeds fine, but I'm really concerned about this. I took the bolt out of the gun and put a live/new round in the chamber and it sits the exact same way as the reloaded, bulged round, and exactly like it should (ie the bulged spot isn't sticking out of the rear of the chamber).

What could be causing this, and is the brass safe to use? It's the same on my Aguila, PPU, and Federal brass, all shot from the same gun though it's less obvious on the Federal and PPU which do tend to come out of the gun cleaner than the Aguila, perhaps due to sealing better.

Edit: I'm asking on here as I've heard some inconsistent stuff on the net - some say it's normal and toss the brass, some say it's a headspace or chamber issue, others say the brass may be fine to reload, etc, so hoping to hear what people on here say.
