Honestly have not mic'd the ID
it feels like .002" ....Tight consistent lock up after 1 pass thru
a Hornady Custom FL Die ....I spray all brass with Pure Lanolin
and 95% Isopropyl alcohol solution ...let it evaporate and rock n roll..
Buy a GOOD spray bottle for a fine even mist ...
BIG Cookie Tray ...keep everything clean...
I forgot add ....remove the expansion mandrel and decapping
rod when doing this ....If you look on my Redding across the body
you will see the FL die with it missing ....
Like butter ....
