380 reloading dies

[Willyboy]

I have just purchased a 380 auto and plan to reload in the future. I load 38/357 for revolver use and use a combined seater/crimping die with no problems. Can I use a combined seater/crimping die such as the RCBS unit or do I need to crimp in a separate operation for the 380 as the dimensions probably are more sensitive for an automatic. I see Lee and others offer a crimping die only for the 380.
Thanks for your input...Willyboy

You can seat and crimp in the same step. All you really want to do is take the bell out of the case and perhaps apply a very modest taper crimp to the case mouth. You do not want any sort of roll crimp. I prefer to seat and crimp in separate steps, but I also load on a progressive, so this extra step is basically "free".
