Miwall sells both new and reload bulk ammo. I tend to pay a little more and buy the new made bulk. Bright and shiny, clean all over.
In the .40 S&W you will find that the primer isn't all that sensitive. Some of my pistols that have had their actions worked on don't always strike hard enough to set off the primers on the bulk ammo in .40 S&W. I didn't have a noticable problem with the 9mm but at the time I may not have had any 9s that had action work done.
