I gave one of my sons a list of what he needed to get started loading for both of these. He did OK with most everything on the list except for powder. When He bought powder they were out of everything on my list So he let the counter guy sell him a couple pounds of 800x. I have not found much data at all for 800x, Is it too new? Or just not suitable for a pistol round? If suitable does anyone have any data. He bought Berrys plated bullets to start but we will be switching to cast lead when those are gone. The bullets are 124gr for the 9mm and 165 gr in 40. What do you all think? DR
