Using a expander mandrel after using a FL bushing die

[LVLAaron]

High power volume ammo. The 21st Century die/mandrels are in station 1 on both 650s. These are strictly for loading. I don't process brass, I send them out, they come back primed ready to load

Edit. All my mandrels, expanding and turning, are melonited. Next best thing to the expensive carbide offerings.

Dumb question... If they're melonited... Do they gall? Does the melonite wear off?

No galling, the surface just gets shiny. Cheap file won't bite the surface.

Do you get them melonited somewhere, or buy them as such?

I add them to the batch when I send barrels in.

Who does this work? I am interested in spending money on shiny objects.

The guys who use a mandrel, what discipline do you shoot? I don't see the benefit using a mandrel in short range benchrest competition. You would need a separate dedicated press to save time.

Or one of these

That is a classy piece of equipment but I envisioned C clamping another RCBS Partner press beside the one I use.

For F-Class and long range BR, I run a mandrel into the next as the last step prior to seating a primer.

When tuning, I try to establish the "better" neck tension after course seating and powder, then fine seating and fine neck tension as I believe the two are very much relative to one another.

We tried running a mandrel into a 6 ppc case and it hit the doe nut.

Doe don’t have nuts. Depending on your 6ppc brass prep, your 6ppc brass will not have donuts.
I get more consistent es using a mandrel after sizing the neck just below the mandrel size. I have not seen enough difference at the target to justify the added step.

I’ve used a mandrel to help seat Bullets in cases that have a donut. That seems to work pretty well.

Where do you guys get your mandrels, and do they come in different diameters for a given caliber?

I originally purchased a set of 6mm and 7mm from field and cave outfitters.
My last set (.22 cal) I ordered from 21st Century.

Seeking a good source for expanding mandrels

Where is a good source for expanding mandrels? CW Edit Explanation, I have a Sinclair expander die and several of the basic expanders for turning necks. I would like to test with different mandrels to "tinker with" neck tension. CW

My buddy bought Dick Whiting's equipment and moved it Austin. Dick's DBA was Mountaineer Brass Processing.. Standard processing; clean, resize, trim, clean, chamfer necks. The new business in Austin is under the name Pop Pop Brass..

I provide the primers and they run them in a dedicated 1050.
