Amp Annealing

[Doublejake]

I have run my Amp in Aztec test and get my code. When I anneal my brass with the code I see NO color change in the neck and shoulder area of my brass. When I used my old flame Annealer there was always a color change… Is it working correctly if I see NO color change?

I don't really see any color change in my Lapua brass either(using the Aztec code,AMP MK II),always still looks the same as when I got it with the factory annealing.

I would have to say I see color difference in my 30BR Lapua brass after annealing it with my AMP, just not as much as you would see with flame annealing. What is your Aztec run code you're using?

From the AMP Website. When the AMP first came out this was a question that came up all the time.

My cases are not showing “annealing marks” after annealing. Why?​

We get this question all the time. Cosmetics are simply no indicator of annealing. It is quite normal for cases to show virtually no marks at all and be accurately annealed. Sometimes it is due to the surface condition of the brass. Freshly polished cases show fainter marks. We almost never see much in the way of “annealing marks” on 6 PPC cases or many other cartridges. Other cases, like the 30.06 family look way over annealed, and yet are exactly correct. AZTEC is extremely accurate. If you are using the correct pilot, and if the cases are coming out hot, they will be correctly annealed.

My 30 BR, Lapua brass 9K Neck, pilot 10, code 122

Thanks John!

If you want to see nice colors on your annealed cases… put a light oil coat on the necks.

These are some of the codes that have worked for me over the years, Different batches of brass are going to have different codes. Keep in mind I ultrasonically clean my brass before I anneal. AMP manual said thats not necessary, but I found it works for me. I've won a lot more shoots since I started using the AMP. I anneal after every firing.

I do not see much if any color in the AMP annealed brass

My 250 Savage Winchester brass shows nice annealing marks, my Lapua 6.5x284 brass necked to 257 not so much, nor my 284 Peterson brass....

I have found that the way the brass is cleaned has an effect on the “color” or lack of. It seems that ultrasonic cleaning in RCBS solution and drying leaves no “color” on my brass. Simply cleaning the necks with clean 0000 steel wool and then annealing shows some “color”. I’m sure if someone has the time to experiment with different conditions of brass they could achieve varying amounts of “color” after annealing.
In the GTAW welding process, welding stainless and other alloys can produce “color”. This occurrence is actually oxidation. I’m no metallurgist but brass “color” at the annealing line makes me think of oxidation. Oxidation in welding can have a negative effect on the alloy’s properties to resist corrosion but man it’s pretty. Maybe apples and oranges in comparison.
I agree with AMP. Cosmetics are irrelevant when brass is annealed correctly.

Probably a lot of strange chemicals in propane. Amps is a clean process. invisable cleaning or lube residue has a big effect on color.

Agree, that cleaning and/or lube residue has a big effect on that color change. I just did and experiment yesterday as I was given some PPU once fired cases from factory ammo to see what kind of color change might occur. I cleaning the necks first with steel wool then annealed them as I do with my Lapua case using the "glow method" in my Annealeez machine. Well, they didn't turn color at all, though there was a very slight hint of the annealing process. I was actually surprised that they looked like they weren't annealed. These PPU cases must have been really clean on the outside!

My brass that has been fired 25 times turns alot darker than fired 5.

Do you clean your brass? When I clean my brass prior I will see some slight color change where the anneal line is. Plus with flame annealer your getting residue from fuel deposits.

Some beautiful work in that picture!!!

Don't see a color change on the 6PPC but do on the 6 Grendel, strange but true! Maybe a "slight" color change on the 30BR.

I 000 steal wool before annealing.
