Purchased a new box of Cor-Bon DPX 9mm 115gr +P. I noticed the casing has a crimp in the middle, unlike my Cor-Bon DPX 38 Spc, or other ammo.
Does this weaken the casing?
Will this affect reliability?
Is this normal?
Is this a defective box of ammo?
Should I be concerned?
Should I return the box of ammo?
