Re: Redding Type "S" dies, are they worth the extra money?

I used Redding FL "S" dies for years before I did an experiment comparing those, RCBS, Forster, Forster factory honed neck, Lee RGB, and Lee collet dies.

The "S" dies are the worst of the bunch, but look the best and cost the most.
The Lee collet die is the best of the bunch, but looks the worst and cost the least.

Can you elaborate?

Did you measure and compare the run out?

Re: Redding Type "S" dies, are they worth the extra money?

I took populations of 10 fired .223 cases from my Ruger #1V.

*I measured the run out of each at the neck with a Sinclair concentricity gauge, and they all looked very good.
*I measured the length of each case.
*I sized 10 cases with each die.
*I measured the run out at the neck.
*I measured the length of each case.
*I primed, charged, seated with a bullet with a Forster sliding sleeve seater die.
*I measured the run out at the ogive and recorded it.
*I fired the rounds @ ~ 66kpsi chamber pressure.


I repeated the process several times and followed the growth of the die dedicated cases.
The brass went into the rifle eccentric and long.
The brass came out of the rifle concentric and shorter, and then came out of the sizing die eccentric and even longer.

1) In general, the pulling of a sizer ball through a neck makes the most error.
2) Next down the line in eccentricity causes is sizing.
3) The tiny effect of bullet seating is also measurable.

All of the above testing was done without any sizer ball effect, pulling or pushing.

Sounds like quite a test. Thanks for posting.

I wonder if anyone else has done similar comparisons?

Re: Redding Type "S" dies, are they worth the extra money?

Hi Guys, I currently have a Redding Type S Match FL set for my 6.5 Lapua. I'm pretty happy with it, but I'm pretty new. I don't neck turn, anneal, etc, yet. I'm shopping for a set of dies for my .338LM, and after some reading in the last 24 hours I'm more confused than ever.

From what I've read, I gather that the competition sets are not worth the added cost, and the the NS vs. FL size debate rages on. What also seems pretty clear is that the expander ball in my Match S die is bad, and that an expander die from KM would be more wiser.

Can I take that expander ball out of my FL Type S??

Thx.

-Jeremy.

ps - sorry for reigniting a 5 year old thread!!!

Nevermind - I built up my nerve and dismantled my FL sizing die. I guess I was just being lazy....

To answer my own question - the expander can't be removed per se, but rather replaced with a collet that still holds the decapping pin, but doesn't expand the neck.

-J.

Re: Redding Type "S" dies, are they worth the extra money?

Redding's and RCBS's full length bushing dies are probably the best commercial ones to resize bottleneck cases. Sierra resizes all their fired cases in the Redding ones for accuracy test cartridges they're available for. Their match bullets shoot under 1/2 MOA in their 200 yard test range; 1/4 MOA or better groups are common. That's as good as short range benchrest aggregate records.

The only other commercial die that is a tiny bit better is one from Forster that they've honed the neck out to customer specs. Such dies make case necks a bit better centered on case bodies because they keep the neck sizing chamber perfectly aligned with the body chamber. Redding and RCBS bushing dies don't do that; their bushings float in a chamber with a couple thousandths clearance. But few people will be able to tell the difference shooting ammo from either one.
