I cut open a couple pieces of brass that bulged in my Lone Wolf barrel, to see where the bulge happened relative to the web of the case. This is a newer barrel, bought in December 2011. I thought the picture was interesting enough to post here.
This is a 40 S&W case, didn't have any bulged 10mm handy, but the internal dimensions on the 10 and 40 are pretty much the same other than the primer pocket.
