Sounds like OAL to me too. Or you've seated too deeply and the case has a wee bulge.
You should never use a roll crimp for .45 ACP. Takes out the headspace entirely. Taper crimp only. And just a wee bit of taper crimp. There's no actual diameter measurement, but you'll see a tiny, shiney, ring on the case mouth that's about a 32nd or so wide.
