The only time I had this issue is when the powder is compressed.

I have been having the same problem with my .380 auto rounds. Here is what I have come up with. First of all you need a case gage for the caliber you are loading. Put a few empty cases (brass) into the case gage and see how it fits. If it goes in and out easily, it does not need to be resized. I have noticed that my 380 brass when resized is too small to accommodate the bullet I am trying to seat, and forces the brass which will bulge rather than resize in the opposite direction. This is in spite of lubing both bullet and case. Your end result should not be shaped like your favorite lady friend, but straight, and should easily fit into the case gage. I have ordered a universal depriming die and will try that out with out resizing since my brass is already sized to the chamber I will be firing it in. I'll post something on how this works out.

So here is how I see it, and what I did to correct the problem. First of all you resize you brass in the first stage, then you bell the mouth of the case when you put the powder charge in to the case, then you place the bullet, lubed, into the mouth of the case and begin to push it into the case, Well this is where it gets dicey. The brass has been resized to where the bullet will not go into the case without having to do some resizing of it's own from the inside. Well your brass may be too thin to accommodate such a maneuver so it squats down and bulges, making this nice little belly at the base of the bullet. Sound familiar? So what is the problem? The seating die gives no outside wall support to the brass and so when pressure is applied to seat the bullet, well you know the results.
I removed the clip that holds the inner parts in the seating die, and removed the inside pieces that actually seat the bullet and put the part that is held in place by the clip back in and ran the die all the way down, with the handle pulled all the way. Then I ran a few of these bellied rounds through the die. Checking each with my case gage. It worked for most of the rounds that were messed up. The only concern I have at this point is did that thin the brass at the belly so that it will separate when fired? only time will tell.
