I assume that was the reason Hornady beveled the base of their 147 XTP. The long length of the heavy bullet (the shank of which is straight) sitting in the tapered case of the 9mm, prevented a bulge where the base touched the case. I only loaded one box of those XTP's, so my experience is limited to that.
I loaded my 9mm Major on a Dillon SDB. Trying to figure out what was possibly wrong, I took the decapping stem out of a Hornady resize die, and ran the loaded rounds through the die body on a single stage press. This only ironed out my taper crimp, and resized the bullet down to under size. If I only ran a loaded round into the carbide ring a couple hundredths and then gauged it, it dropped right in. So, my bulge is up at the bullet, not at the extraction groove. For the most part, this happened with R-P and Geco brass. Win, Speer, FC, and PMC. for the most part, worked ok.
If I can't find bevel base bullets, I guess I can cull my brass, and follow up with a step on my single stage press.
