This photo looks close but my bulge is closer to the base than to the top.
I can see here in this photo that the bulge would show the bottom edge of the bullet inside the case but the bulge I'm talking about is lower - closer to the base.
I'll try to get a photo to post. Not quite sure how to add a photo here but I'll see what I can.
As for the bulge. I'm guessing that it is probably about the same amount as shown in your photo, just in a different place. On mine, you can actually feel it more than see it.
