Sac 6 bra die

I have the .266. Ordered the .263 so I can run my expander mandrel. .266 left some necks a little looser than I liked. With alpha brass.
 
Thanks.Curious on your results.Are you annealing each time?I get a .269 neck on loaded new brass.Getting ready to shot brass first time.
 
No annealing yet. I didn't do any loading last night. Work kicked my ass. Just ran 84 through the die, going to clean em and then start expanding later this afternoon
