20P Dies ?

[223Randy]

Has anyone tried a set of Lee Collet dies for the 20P? I am thinking that i might use a Redding type S to get the neck to a smaller dia. then finish with Lee Collet die in 20 cal so that the inside of the neck is more consistent in dia.

Don't you have to special order those from Lee?

I just turned another stem for my 223 collet die and use that. One step.

The stem is still full size at the top to center it in the collar, but "steps down" where the collets press against the stem.

It helps to anneal the cases before sizing.

I would just run a mandrel in for evening them out. I have mandrels in different sizes to control tension. I use a bushing just small enough that the mandrel just barely touches them to even them out. Matt

I resize my necks in two steps then run them through a 21st Century mandrel.

I first use a Lee 204 Ruger collet die, which I trimmed down to the same length as the 223, then run them through my Redding 223 bushing die, after that I just use the Redding bushing die.

I have a Lee Collet die for 20 Practical. It was a special order from Lee. But I don't use it on initial forming of 20P brass. Right or wrong I do my forming in 3 steps. I run fired brass through my 223 FL sizing die with the expander removed, next I run them through a Redding 223 FL S bushing die with a .235" bushing, and I finish using a CH4D 20-223 die. Gives me the straightest necks and best formed neck/shoulder junction.

After initial forming, my process can change based on what they were fired in.

I think i may not have explained the process i plan to use.
on first fired 223 brass -
1.full length resize and deprime with Lee 223 Die w/o turned down mandrel
2.neck down to something smaller than 223, larger than 20 cal., with redding S neck die
3.Finish to size with modified 204 ruger Lee Collet die

Load, shoot, neck size with Lee collet die, load shoot, repeat

Same here just trimmed the 204R collet body to 223 case length dimension.

6PPC collet die can be used as-is for 6BR, I made a spacer to use the 6PPC die with 6TCU on a Forster Coax. Get 'em quick they are discontinuing the 6PPC collet die.

BTW std non-bushing Redding 223 die will take the necks down to ~.238" if you remove the expander button.

When using my Redding dies (full length or neck sizer) after fire forming, I leave the bushing a little looser than normal so I don't crush the shoulder. Plus I have the proper size 204 expander for .002" tension for my bullets in LC brass.
