full length sizing/ neck sizing

[F. Guffey]

Just me but I use a Redding body die followed up by a Lee collet. I generally have less than .001 runout

I have body dies, not a problem for me but my body dies do not have a shoulder, because? they are body dies. When I add the ability of the die to size the body of the case and size the shoulder at the same time the die is no longer a body die.

There was a time before the bushing die, that was a time when I was the only one using them; meaning sizing the length of the case from the shoulder to the case head without sizing the neck of the case is nothing new.

Back to the Redding bushing die, I never read the part where the reloader adjust the die to size the case and they always leave out the part about the sizing of the shoulder. With a bushing die part of the shoulder does not get sized, that would be the shoulder/neck juncture.

I need a little help from you. Can you explain why when using a .336 bushing die , the neck measures .333 OD , I called Brownells there answer was , there are other variables , spring back & brass thickness . My way of thinking is a .336 bushing should give a .336 OD or am I missing something ? I'm not one who minds asking someone who I thing knows more then me. Thank You.

I have no infatuation with spring back, snap back or jump back;
I do not spend a lot of time worrying about something I can do nothing about.

That's sorta like saying that you can't stop the rain... so you just get wet.

Meanwhile (for the rest of us), we look at the resultant case headspace
measurement after sizing and change the feeler gauge to accommodate
the springback.

It's also sorta like why God invented umbrellas... for the thinking man.
