Youch!
We're opposite- in that I don't reload for our handguns (haven't found it to be cost effective)...so I don't know the specifics about crimping handgun cartridges.
So no offense if I'm stating the obvious to you- you are aware that over-crimping can increase case pressures to a dangerous level?
We shoot both bolt and semi-auto .223's, and I do not crimp for either.
I realize that some do crimp particularly for the semi's, as they have concern about bullets coming "loose" from getting loaded and jarred around in the mag...but I've never experienced any of those issues.
Just a suggestion to proceed very cautiously when crimping a high-power centerfire round. If you're going to crimp, you need to start with a very light crimp- and if you feel it necessary increase the amount of crimp incrementally, watching for overpressure signs. No different that working up a load...
