.357 Sig

Howdy fellow Americans! I am about to start doing 357 Sig. For those who are experienced doing them, please tell me if there are any. tips, tricks, or anything else I need to know. Do I flare them, or do I run a trim die on them, for a bevel, before seating a bullet?

I will be using unique . I will be loading either a 115 grain, or a 124 - 125.

Remember to lube your cases and yes you flare them. I'm loading xtreme 124 fp with unique and a lee factory crimp die on a Dillon 550C. Works flawlessly in my pistols.
