Amp Annealer Changing POI

[Mikecr]

I actually did recently. Used the amp , Aztec mode. Burned one and used the produced code. Annealed 200 pcs . Seated bullet with .02 interference. I could then push the bullet deeper with my fingers

That sounds like fully annealed instead of process annealed(useful stress relieving).
You know what you can't over anneal with? Salt Bath dip annealing.

The Aztec intentionally burns one for testing, analyzes it, and sets the time based on the results. Unless something is broken with the AMP it should never over anneal.

Is it possible it's just a coincidence of timing with something else going on?
In other words, have you rechecked accuracy without the annealed brass to ensure your groups are still great to eliminate something going on with the rifle and not the annealed brass.

I've been reloading a Winchester 270 with 117 grain hammer hunters, using Hornaday brass. I'm full length sizing and using a mandrel to size the necks, and found a great load using 58 grains of R16, .030 off jam....pretty much one jagged hole. With components so scarce, and with dreams of superhuman consistency, I purchased an AMP Annealer. Well, my perfect groups spread out like an egg hitting the floor. Not terrible, but from excellent to say 1 1/4 moa. Should I restart working the load back up to see if the nodes changed....or just mess a bit with the seating depth a bit. Anyone else experience this when they started annealing? I'd hate to re-work the loads on all my rifles...not pretty.

With no other changes to the load it has to be that the neck tension changed. Easy fix.

I had to work up a new load when I started annealing. Some here may be right and it needs a minor change to get back in the node, but I would start again from scratch.

Do it every time and nothing changes
Also resize after you do it so the Tension stays the same

Right, but going from brass with a few firings and having not been annealed to brass that is annealed every time may require the load be adjusted.

If OP saw their load deteriorate after starting annealing I would develop the load from scratch.
