Hi All. I'm confused about Winchester 147gr 9mm ammo. I have some 147 grain PDX1 ammo that states on the box that it passes the FBI testing requirements. I also see reference to the Winchester Ranger 147gr T-series Law Enforement ammo with the "RA9T" code on the box. Are these the same loads in different boxes? Are both bonded ammo? And, are both of these the latest generation of ammo from Winchester? For better or worse, I would like to use the same ammo the FBI selected. I think they use .40s though??? I wonder if some agents use 9's and this Winchester ammo is what the FBI selected for them? I have some medical issues and like the low recoil of the 9mm over larger calibers. I would like to use the same ammo the FBI chose for 9mm (if that exits). I have researched this but the more I read the more confused I am! Can anyone shed any light on this? Thanks!!!
