redding full lenght bushing sizing die question?

[kevin9934]

I am currently necking down my brass and i found that my neck is not resized to the full lenght i am looking for.

I have the redding bushing full length sizing die installed(tested loose and tighted bushing) on my forster co-ax.
I have adjusted the die to touch the jaws. Maybe the issue is the jaws?

I have measured approximately the neck portion that is resized : 0.260

These dies are not meant for " necking down" They are meant for neck sizing after shooting. Get a non bushing FL or Neck die for necking down the entire neck.

The bushings usually size only the upper part of the neck. Some of the cause is the construction of the die, some might be in the bushing itself. .260 sounds like a normal amount of sizing. That has be sufficient for all my BR and Fclass shooting.

I have never used full length bushing dies, but have used neck bushing dies, both arbor press & reloading press types. Nor have I ever used a co-ax press. I have, however, used RCBS Rock Chucker, Lyman Orange Crusher, Lee & custom arbor presses over the past 35 years.

Having gotten that disclosure out of the way, what brand of bushings are you using?

Forster bushings will not work in Redding neck bushing dies & vice-versa or Wilson bushings in Forster dies; perhaps the same goes for the full-length bushing dies.

NormB : Look enough for me too. With my neck turned finished brass sample the neck to shoulder mesure +- 0.284 so i'm left with only a portion .024 unsized. I don't know maybe i should buy a shellholder adapter for my forster press and test it out.


jamesharrison : I'm using redding steel bushing for my redding die. I will receive my TiN bushing this week to test.

If it helps, I use Redding Competition Neck dies, with the micrometer and Redding Titanium bushings. At one point I was only sizing a portion of my necks, it took some serious resetting of my dies/press, At least with the micrometer I was able to easily adjust the die to get the whole neck sized. I started with fresh brass, took once fired cases for reference, and rechecked everything, in the end it was a few turns and recheck of measurements to get the brass sized the way I wanted it. In the process I reset my body die, as well as the seating die. My final product is much more consistent now, with less work happening to the brass. I'm also paying much more attention to OAL of the brass and headspace, and trimming more often

The TiN bushings are much better than the steel for not scratching your necks. Because the bushing sits on a step above the shoulder/neck junction in the die, it can't size all the way to the shoulder/neck junction on the case. If you can adjust you S FL sizing die body to just touch the case shoulder with the Foster C O AX press as it is, you won't be able to size the neck further down with a different shell holder. Bottoming out the bushing holder is as deep a neck sizing you can get. I wouldn't bottom it, I leave just enough room so the bushing can rattle a bit. The neck will find the center and not be held to one side if manufacturing tolerances stack up.
