I've searched and read lots of threads on this topic without a clear resolution. I'm loading .45 ACP, with Zero & Montana Gold 230 FMJs. I get a bulge in the case where the base of the bullet sits (not at the base nor 'Glock' bulge). I acknowledge they fit and function fine, and there is excellent neck tension. Still, I can't abide a bulge in my cases. I've tried Lee, RCBS and Lyman sizing dies and it's the same with every one. Brass brand doesn't seem to matter much either. I've also expanded a little more to help the concentrically of the seated bullet, and that didn't help either. What's the next step? Match-grade ultra seater die? A different sizing die? Factory ammo doesn't have this bulge at all. Thanks.
