I've generally always felt it was better to do it right the first time, than to do it over, or use some special tool to fix what you shouldn't have screwed up in the first place.
I would like to see a picture or three of the "bulge" the OP is concerned about.
Sometimes, everything can be "right" and you still see a bulge, but unless it creates an issue chambering or firing, its just cosmetic.
The sizer die squeezes the case down to slightly below min specs for the cartridge. Sometimes, its more than "slightly", and this can result in a visible bulge when you seat the bullet.
Long ago I got a set of Lee .357 dies. They worked, ok, but the sizer die was so "tight" that there was a visible "step" where the die stopped just before the solid head of the case. And those "over-resized" cases usually had another visible step, where the expander stem stopped. Which often was more pronounced after the bullet was seated.
It didn't affect the shooting in any way, but to me, it looked fugly, and I felt the brass was being overworked. My Lyman dies didn't do that, my RCBS dies didn't do that, that Lee sizer got tossed into a box, and I haven't seen it in decades. I do use the seater die from that set, though. I use it for those rare times when I load RN lead bullets. Its simpler and easier to swap out the already set up die than to change the seating stem and adjust it.
Either the OP is getting bulges because he's not seating his bullets correctly, or possibly he's seeing a bulge because the case is sized in a "tight" die. A picture would be an enormous help to understand what he's seeing.
