Primers came in commercial-style white boxes, not the usual blue packages I've bought in stores/other online sellers. I found some of them protrude slightly outside the base of the primer pocket in some brands of foreign-made military/range brass, even after reaming out/swagging the primer pocket. This might cause accidental discharges if the slide hits them during cycling of rounds. With Star-Line brand brass, this was not a problem as they went completely inside the primer pocket. Primers were packed properly and arrived on time as promised - no complaints here with purchase or service.
