Well if you don't resize the neck, you'll defenatly notice some lost neck tension.
Depends on what you wanna do with the ammo. It won't be your best target stuff, but it'll be ok for plinking/trigger practice.
txspike an zoner pull the pin, I've gone to a Lee universal decapper so the pins are out of all my sizing dies.
I'll use a little of Lees resizing lube for a job like this, it doesn't require washing and when dry does not affect the powder.
