Crimp or no crimp on 9mm?

[Smokedurhonda]

General survey/ question for reloaders, to crimp or not crimp 9mm? I know this has been beat to death in other forums but an looking for a definitive answer. I have a chance to get a lee 3 hole turret press for cheap, and that would mean running them all on a single stage to crimp- which isn’t a big deal.

Me ....personally I crimp everything. Might be more out of habit. Was taught to crimp, so I crimp. Lol. Of course I reload for general use, not specific firearms.

I definitely crimp 9mm. If you don't you run the risk of the round not chambering correctly.

I crimp just enough to get the bell out. You could get the seat/crimp die

100% crimp
Lee FActory crimp die is the best, as it is the only one thaqt resizes the entire loaded round as it crimps

Not only that but the chances of bullet setback in the case will also increase pressure. Test have show that over time that even loads that are taper crimped that are repeatedly chambered such as those used for SD ammo tend to have gradual bullet setback.
