Doing an inspection on the brass prior to reloading, it became clear that not all brass is created equal.
Not a very good picture, but you can see that the bottom cartridge (Remington) is shiny brass from stem to stern. The Privi cartridge at the top is brassy up to around the neck, and is then some sort of dullish silvery metal.
Question for you reloaders out there: should I use the Privi? It shot great new out of the box, but this looks somewhat odd to me.
