Funny this would pop back up. I started reloading 223 for the first time a few weeks back and sure enough, I got a case stuck in the full length sizing die...BIG TIME (Lee die). It was a serious pain to get apart. I had been hand applying Dillon lube and apparently, that isn't slick enough, or something.
On a whim, I used th small packed of Lee lube that my die set came with and it ran a-ok...but seriously messy stuff.
One thing I did not do was lube in inside of the neck...when you guys do this, do you re-rumble afterwards? How do you get that lube back out of there so it won't interfere with the powder?
