My Lee die is roll crimping my 30 carbine ammo. I thought all semi-auto cartridges were supposed to be taper crimped. What's going on with this Lee Die? It came in a set of three.
Why would you consider then giving you both style crimps bad? It's not their fault you didn't read the literature. You need both with the 30 Carbine because when shot in a revolver you can experience bullet pull thus the roll crimp capability.I went on the Lee website and I think I have my answer. Lee dies evidently taper crimp and roll crimp both. They lightly taper then roll. Not at all useful for a cartridge like a 30 carbine. A little too much crimp and you end up rolling it. Probably a cost cutting feature. Maybe a good reason to pay a little more for a better die set.

I don't have a .30 Carbine revolver, but wouldn't they headspace on the case mouth just like the rifle versions?
I have a set of Lee .30 Carbine dies and have never had crimping problems when loading for several military and commercial ".30 US Carbine" type semiauto rifles.
The .30 Carbine is one of the rounds I never crimp. If I did I would use the Lee FCD mildly.
Unless I'm loading cast bullets, I don't crimp 9mm or .45 ACP. I don't load many jacketed bullets in those calibers, but the ones that I do load seem to seat fine without setting the expander die low enough to actually start Belling the case.Why are you trying to crimp a non-cannalured bullet anyhow? Particularly into a case that headspaces on the case mouth?
I think taper crimping a non-cannalured bullet is pretty common. I taper crimp my 45 acp and 9 mm for obvious reasons. I don't really see any difference between 30 carbine and those cartridges, they all seat on the case mouth.
