I am reloading for 7.62x51 for my AR 10 platform. I have been searching the local reload shops and websites for .308 projectiles. When I look up .308 projectiles for Hornady, Berger, Nosler, etc; I only see .30 caliber (.30 diameter) projectiles. I have bought .308/7.62x51 ammunition(Remington, Hornady, Fiocchi, Tulammo. They all measured .30 diameter.
What gives? Whats going on here? Do I need a true .308/7.62 diameter projectile to fit the wider lands in the barrel? (Where does one find them?) Is the .30 caliber diameter projectile still grabbing the narrower lands in the barrel?
