Crimp or no crimp on 9mm?

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

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.

Exactly! That's why I rotate rounds in my duty pistol. [emoji106]
