Annealing order of operations?

[hoverp]

ive tried it both ways , (so to speak), as far as annealing after the SS media cleaning and before the media cleaning.

the thing that I settled on was
1. De cap
2. anneal (Giraud)
3. SS media clean
4. Lube, resize (flull length sizing but no expander) custom honed Forster FL die for proper neck tension of my 6XC. .0025
5. Trim (Giraud)

The reason I went to annealing prior to SS cleaning was to get rid of the oxidation of the annealing process on the inside and outside of the case. I didnt want this affecting bullet seating consistancy from the internal neck oxidation.

The SS media works great on cleaning the neck out and I see no residue from the annealing sooty necks.

My problem is due to the SS media I need to at least chamfer the inside of the case mouth prior to reloading due to the peening of the sharp edged case mouth that the Giraud leaves after trimming. I trim to case trim length and the cases dont grow enough after one firing to have the Giraud trimmer get the mouth. It takes about 3 firing to have them grow enough that after the SS media cleaning and sizing I can actually touch the mouth with the trimmer set to 1.900 case trim length.

So that means in order to get the inside mouth chamferred properly I need to do each case by hand. I might just buy a powered chamfer to just hit the inside so I can load and then use the giraud when I need to get the overall case length back to 1.90.

anyone else see the peening from the SS media?

First, I clean don't want dirt and grit in my dies. Second, I lube, full length size and deprime (with tapered carbide expander). Third, I trim. the second and third steps are done on a Dillon 550 with Dillon case trimmer. Fourth, I clean the primer pockets, and chamfer the inside and outside of the necks (with Hornady case prep station). Fifth, I clean again removing all lube. Sixth, I anneal in a Bench Source annealer. Seventh, I prime my cases, Eighth, I fill my cases after measuring the powder on electronic scales, Ninth, I seat my bullets in a competition seater die. Tenth, for those shot in a repeater I use a taper crimp die. I load all my longrange ammo on a Dillon 550 using John Whidden's CNC solid, floating die tool heads.

Just a short question

"I load all my longrange ammo on a Dillon 550 using John Whidden's CNC solid, floating die tool heads. "

How does the ammo compare with that loaded on the standard tool head. Does it really reduce run-out as much as claimed? Any readings for the "standard" and "whidden"?

Just wondering.

I think they are superior to the Dillon tool heads.

p.s. John this should be worth a couple toolheads.

OK, I'll accept that. What I was interested in was there any quantifiable differences between ammo loaded on the original vs the Whidden tool heads. Yes, I know they're machined to tighter tolerances, have the floating die bushings, and the Unique-Tek tool head clamping system installed.

But what actual measurements did you see between the results of using the two different heads. Did it reduce the runout to zero? Reduce it by 25%, 50%, etc.

I know that the stock toolhead on my 650 does a far better job with the Unique Tek clamping system installed. I get finished .308 rounds with .0015 max TIR and as low as .0005". Curious how much better the Whidden's are in your experience.
