7SAUM neck bushing?

[patchhound]

I just went to order some dies for my 7saum and reallized I got no clue what size bushings to get. The size of the new brass is .314 but I dont want a factory death grip on my bullets. I never used bushing dies so it`s all going to be new for me... The reammer my smith just got is a Clymer factory rep. 7saum so I guess the neck is .320 and I really dont want to wait till its done to see what I need. Can anyone help! Also, how do I staighten out the new cases if I dont have an expander?

You will have to check the neck of a loaded,dummy) round and then follow the die Manuf. procedures for bushing size fitting. Redding has some very helpful info on their web-site.
I usually leave the expander button in the die until I run my new brass thru it. Then remove it before I re-size any fired brass. Hope this helps. Bill

Thanks, I learned a lot of stuff on Redding`s web site. Would of never thought of goin there...I can call my `smith tomarrow and find the neck size with a seated bullet, just -.001 and start around that.

How will the 'smith know the thickness of the brass you will be using?

He will only be concerned about the total overall measurement
,diameter of the loaded round)
