I don’t anneal for the affects on group size per se. I anneal to extend the life of the brass. The fact that it’s in the exact same condition every time I reload it is a variable I now control.

No one said annealed is dead soft.According to who?
Are you referring to the fact that an AMP machine can do that? Or claiming that’s what they always do? Or what, and based on who’s data? Certainly not AMP’s.
If you pedantic geniuses are right, that annealing is only one thing, dead soft, and there is no in between, then there’s no reason to buy an AMP or any other annealer; just heat with a torch till it glows and call it done. That’d be fully annealed after all, and apparently your “ideal” condition.
Of course sooner or later you might figure out that there are situations where dead soft brass doesn’t work well. Something about semi autos, bullet setback, runout, that sort of thing.
You can prove that your fully annealed brass works well in some conditions. I wouldn’t even argue with that, and the idea that fully annealed is most consistent is right. No issues so far. But once you encounter conditions where that doesn’t hold a bullet adequately, it’s hard to claim that fully annealed is always best. It’s just not.

Except that none of the data posted here or elsewhere supports your claims. Ignoring the reality of how most people use heat to PARTIALLY reduce the hardness of cartridge brass, but not dead soft, and refer to that as annealing, is just asinine. You’re either being so pedantic that it’s just stupid, or you’re flat out wrong. Which is it?
If it doesn’t hold a bullet properly, it’s not annealed.
It has started messing with the zinc content.
Again, this is all very, very simple. Annealing is a state in which there is recrystallization.
Before recrystallization, not much worth while happens. And if you heat long enough, you start melting things. That’s what’s happening when people say “over annealing.”
You just don’t understand what’s actually going on and making up your own idea.
What’s happening here is you actually don’t understand what annealing is.
No, what’s happening is your words don’t match reality. Whether they match what you’re thinking is the question; are you just complete crap at communicating or just full of crap? Or, as said earlier, so pedantic that it’s just stupidity? Do you even have a point, other than to argue about the definition of annealing?
You can see from the chart, things start to change in the brass before recrystallization is reached. Then platuea somewhat after it starts.

So like 90% annealed seems to be the goal?
There it is. The number one trap of these academic discussions. People draw conclusions based on the numbers and theory.So like 90% annealed seems to be the goal?
I was actually being facetious in my oversimplification.There it is. The number one trap of these academic discussions. People draw conclusions based on the numbers and theory.
You know the real goal of annealing? To extend the life of your brass, uniform the shoulders and necks, and to improve the results on your target.
That last part, is where the focus should be.

I don't guess at anything.Not having the equipment to actually measure exact hardness we guess at that number.
Keep in mind most are not as blessed as you.I don't guess at anything.
I setup the annealer, shoot a test. Change the time on the annealer, shoot another test. ... and I continue doing this until I find the exact best performing setup. The target tells all.
However, I get that it's more fun for most shooters to just argue relentlessly in 500 post long threads because they can't shoot at their house. They have to drive to a range... so they don't get to test much of anything really. So disparaging one another when neither party has enough experience with testing the variable becomes the norm. Shout shout shout shout shout... with no one providing any targets or test results. lol
Y'all need Jesus. For real.
Sounds like "partially annealed." I.E "Recovery-A low-temperature annealing heat treatment designed to eliminate residual stresses introduced during deformation without reducing the strength of the cold worked material. Would help stop necks from cracking.Also in the definitions:
If you don’t get to recrystallization, you can’t reverse any of the cold working.
In the meantime the tension in the thread is rising!
Yes, this thread needs annealing…
Even a person that is an experienced reloader and metallurgist (camp 1) can examine an experienced reloader annealing (camp 2) and explain it in better detail than the reloader himself. The OP was close but he is not an experienced metallurgist with brass annealing for reloading. I think this guy can save us a lot of time if you have about 25 minutes to kill. It is not rocket science.Perhaps this thread should be separated into 2 competing threads:
1- Based entirely on scientific studies and backed by labs with the requisite testing methods and confirmed results.
2- Based on purely experience based methods and proven with targets and ES reports.
We have two strongly entrenched camps and I see merit in both. In the meantime the tension in the thread is rising!

As you should be able to deduce from the temperature chart, from 500-700 degrees the tensile strength decreases rapidly before recrystallization begins.
I.E It looks like 675 would be a very bad temperature for recovery annealing if tensile strength reduction was a concern.
"The amount of change before recrystallization is not enough to matter and sometimes it gets slightly harder."
I am failing to find in the study where it says or represents this.

You should ask for your blessings and act on your faith to have any expectation of receiving the blessing. If more wanted to live out in the wide open and shoot out the window... they can.Keep in mind most are not as blessed as you.
What hardness have you arrived at as optimal?
Its cause its too cold and dark up there in the arctic.You should ask for your blessings and act on your faith to have any expectation of receiving the blessing. If more wanted to live out in the wide open and shoot out the window... they can.
I have no idea... I don't do hardness testing. I do target testing. A setting on the machine produces a result on the target. I adjust the machine until the target shows the best results. That's it.
After reading all the discussion in this thread, I'm on the fence as to whether I "need" an AMP annealer or not. I'm currently using an Annealeeze flame annealer, but given all the seeming apparent complexities for a proper brass cartridge anneal I'm probably just going to get the AMP when they are back in stock and eliminate all doubt.
What is apparent to me from the last page or so is there is a target brass hardness at specific places on the cartridge. Whether this is a partial anneal or a full anneal is almost a moot point as AMP and the brass manufacturers specify a target hardness. The goal for reloaders seems to be to get a consistent neck tension and to prevent brass fatigue and cracking.
I don't recall seeing any results on target.That’s pretty much in in nutshell.
If you watch the video above, you’ll see cases sitting in flame for 20sec and still have resistance when seating.
So, an “over anneal” is almost not possible unless you’re really trying.
Well I'm still somewhat a newb when it comes to reloading so I could very well be wrong, but a seating pressure of only 10 to 20 PSI would not give me a warm fuzzy especially if I'm shooting it in a semi-auto. It'd be interesting to run some of those "over" annealed rounds through a semi-auto and see if the bullets stayed put when chambering. I suppose if you hand fed every round in a bolt action it might work OK.That’s pretty much in in nutshell.

I’m going to make a slight distinction that I’m not sure anyone has made. Or maybe I missed it, I don’t knowI don't recall seeing any results on target.
There might be resistance enough to hold a bullet... but I'd bet dollars to pesos it won't shoot well.
For the purposes of accuracy and precision, you can certainly over-anneal.
There is a third camp that choose not to anneal.I’m going to make a slight distinction that I’m not sure anyone has made. Or maybe I missed it, I don’t know
If you were to change that one aspect of your entire process, newly fired case to loaded back into a chamber, you would probably see a different results. But you would not have optimized any other factors in the process to account for a different brass anneal(I know, everyone else. Spare me for now). Who knows, you could find something that makes your ammo better or your brass could end up lasting several more firings.
This next part isn’t directed at you, I’m just putting it out into the ether. It can also apply to lots of other scenarios in the firearms world
I find it very discouraging that even glancing in the direction of this sacred cow is met with screaming and insults. Just saying, “I’ve reloaded for a million years and this is or isn’t my process” doesn’t necessarily mean anything. I thought some new info would have been pondered for at least a few minutes
Sorry, I’ll take my little soap box and go home now
They may benefit from the discussion tooThere is a third camp that choose not to anneal.
For them it is just more time suck.They may benefit from the discussion too
Is this where the discussion should turn into an argument and we call each other fucking retards?For them it is just more time suck.

What do you mean here when you say you can bring the load back in tune via a rework? Are you talking about work hardening the necks or re-developing a load?My testing has show that as long as you don’t soften the case head, and the neck will hold a bullet, I can always bring the load back in “tune” via a rework.

A bench source with a swirl flame torch is the cheapest way to do it right.Orkan
I may have ,no I did, miss which set up so please forgive me. But which annealer set up would you recommend someone getting into that doesn’t have endless funds but wants to do it right?
