I'm hijacking this thread. Been reloading for a year and a half and all the brass I've used was from factory ammo I fired and saved. I just bought 100 pieces of PPU 6.5x55 new brass and wonder if I need to size it first? The rifle I load this cartridge for is a CZ 550 American.
Yes by all means! And be sure & check the case length on every one of them! Just an easy way to avoid hard to explain problems!
Ask me how I know:)
