Complete annealing?

[MarkInPA]

What I have found with annealing is that unless you anneal after every firing and work your load up doing this, it takes one firing on each case to get back to where you were accuracy wise before annealing . I have used carbon lube in the neck and still had to get one firing on each case before I was back to where I was accuracy wise. JME

Thanks for sharing your experience. It gives me something more to think about. How many firings do you do in between annealing?

If you get the brass up to its anneal temp (glow) consistently then your annealing properly.

That's a BIG if and no way to quantify that. That is where the faith comes in.

I had been doing appx 5 . But now I will decide if to do it at all or wait till I see problems or do it after every firing and work the loads that way.. I find the same takes place when I tumble but to a lesser degree. I guess before I come to final decision I will test more. Where I have seen this happen is in both my 6mm BR's and my PPC. Brass used is Laupa and Norma.

Listening to this it sounds like y'all think the only way to anneal is with the AMP or not at all!!?? I anneal after every firing using the EP machine and use the glow method. I've got brass on 15 reloads and many loads that run in very low single digit SDs. Is it perfect, no. Is anything in the reloading process perfect, no. We all have our processes and I'll stick with my proven method. Just be safe and do what works best for you. Using the EP machine allows me to control the flame in a couple of ways and allows me to control the timing exactly the same in each piece. I usually sacrifice 5 pieces of brass as testing/setup brass to get the timing right. Watch the tutorial videos on the EP site as he gives some great advice regardless of which flame machine or process you use. Anyways….. good luck and hope you find what works best for you. Happy Turkey day gents.

How hot does the brass get when its glowing?

Not me, I just use a propane torch and a drill motor.

Same here. I use a EP Integrations machine. One of the best $230 I've spent in my shop.

Should be around 750 as soon as the neck begins to glow if I remember correctly.

@JAYgs8163 "Should be around 750 as soon as the neck begins to glow if I remember correctly."
That sounds right, thank you for the reminder. Once it glows its annealed. Propane torch annealing works just fine. I use a hand drill with mine, 1in flame, dark room, 6 seconds rotating and it starts to glow and remove. I can tell the process works because my shoulder bumping stays accurate and consistent within a few thou. Without it was all over the place, even full length sizing unannealed.
