1680, Rem. 6.5s, and those 40gr. Sierra Hornet bullets, or the 34gr. Midsouth HPs they sell real cheap. Even Remington component Hornet bullets work pretty well.
Like Scott F said, don't size but an itty-bitty portion of the neck, and DO use the Lee Crimp Die.
My Hornet rivals my .221 Fireball, and that's my most accurate rifle. Sweet little shooters, those.
