When I got my die set I had to order the bushing separate. Mine did not come with the bushing. But then mine was custom one of a kind set. If there is no bushing in the die and the nut that holds the bushing in place is to low it will do that. But as you said you used it to neck up the brass. Its hard to nail it without looking at the die.I will have to look. Its the way Whidden sent it. I first used it to resize the 270 brass(neck up to .30), hydro formed, and then ran it back through the sizing die again.
You need a bushing! It would neck UP with the 30 expander.I'll get it figured out. This is my first time using bushing dies so i may practice with some 30/06 brass... I have thousands of those! Sure i'm going to loose some until i get it figured out.
I have a redding bushing dies to form 20 vartarg from .223 but i use it with out the guts so never used bushing yet.
Did you adjust the de-caper down at all to de-prime the brass after hydro forming?I sent you a message already asking for advise on bushing size but you can respond here if you want. I never thiught about it not coming with the bushing. Just assumed it did.
Whats weird is it sized up but then crushed it after it was hydro formed. What did it hit with no bushing in it? Why didnt it crush it when i necked it up?
