I haven't had any problem with bulges. I haven't loaded many 380 but I do know some blowback actions can shred brass.

Above is not needed with 380, just 9mm and above. And its not about buldges, its about pancaked head base rim dwn @ primer area. Just last bottom 1/4 inch is what these tools are made for. Takes 2 arms to push some of nines thru above dies in a rock-crusher rcbs.

I've never worried about my 9s, if the case looks slightly off I toss it in the recycle bucket.
I have worried more about the unsupported chambers in the 40 and the bulges it causes. To the bucket...

Nines create problems in those micro pistols ive had. I do the 40's and 45's this way also. Hell, been off work 2 days cause of snow.
