using a body Die or Full length Die

[marine one]

Good morning everyone,
Got a question for you re-loaders out there who uses a Mandrel to size the neck :
After using a full length die, I us my mandrel to open neck to size I need, but if I need
to bump back .002, I have to use mandrel again to open neck.
And if I have to trim my cases, I save that for last step.
This is what I do when using a mandrel. Can anybody comment on this ?
Thank you for your response.

FL size.
Expand with mandel.
Trim.
Chamfer/deburr.

No body die, no more sizing, get the sizer set up correctly in the beginning before you do anything else to the case.

There are several ways to do this. Standard dies can be raised enough to give you only .002 shoulder set-back or the dim you desire, which is what Walkalong is saying. Leave the expander stem out and use the mandrels after.
Then there are these shellholders. I thought these were some sort of gimmick for quite a while until a friend got a set. We got exactly .002 with the middle of the set on his 28 Nosler. If you've got a standard press that uses shellholders, these are pretty slick.

I'm still using the full-size die method without the set, because, eh, why bother? It's second nature now.

Thanks Walkalong, I couldn't figure out, how I was going to do this without sizing again.
I understand now, adjust my full-length to accommodate the sizing and the bump in one step.

I'm using the Redding competition shell-holder, it works out fine
thanks

Redding full length bushing style sizing die, and competition shellholders. The nice thing about the bushing style die is that if you leave out the bushing, it is a body die.

You can pick a bushing that gives you the desired neck tension, or one that is just slightly smaller and then follow up with an mandrel expander, which is what I do sometimes. Either way, you will still work the brass less than most normal sizing dies.

I do exactly as walk along states. Fl size first for all size reduction required and once finished open the necks up with a mandrel. Trim debur and chamfer.

After resizing and using Reading competition shell holder, I found my self not working the brass as I use too. As walk-along said.
But what I did find out that when or after I use the mandrel my cases over all length reduced in size, .002 to .003 don't know why.

 

[Walkalong]

A .002/.003 difference in OAL with rounds is nothing. And of course we want to know where the ogive is in relation to the rifling more than we need to know the OAL. As long as the OAL fits the mag and feeds, it's fine. Some people sweat how far their bullet is from the lands way too much, but it is something that is very handy to know.

Sizing the brass (to a smaller diameter) causes the brass to lengthen, I guess it makes sense that if you expand it, it shortens.

Disregard my post above, I read that as a loaded round OAL for some silly reason.

@Toprudder has it.

It's the opposite of the sizing die and chamber. When you increase diameter it shrinks. When you size it smaller in a die it grows.
