I'm pretty sure the .40 is designed to headspace on the case mouth, but if I have any problems the next time I shoot these loads, I'll certainly try a slightly longer overall length so that the bullet shoulder isn't flush with the case mouth.

There's also the slight possibility that there may have been imperfections in the case mouth openings on these two cases before I even loaded the rounds - just enough to catch on something. I'm pretty good about inspecting my brass, but I'll pay extra attention next time.
