We find that the best results are obtained with this sequence:
Many of our customers use this cleaning technique, so we have run some detailed testing on this subject.
The short answer is no, stainless steel tumbling has no effect. For more detail seehttps://www.ampannealing.com/articles/40/annealing-under-the-microscope/
Note: If you are using stainless steel media for case tumbling, you must be certain to remove all media from cases before annealing. If any media dislodges inside the annealer inductor well of a Mark l annealer, it will be heated to a very high temperature during the annealing cycle. This will melt the bottom of poly carbonate inductor cradle and ruin the inductor. The ceramic insert of a Mark ll protects against this, but it is still important to avoid dropping pins into the inductor.
If you are full length resizing or shoulder bumping you should check your die adjustment. After annealing with AMP you will have zero spring back, and you may need to back your die out a fraction from what you have been using when resizing unannealed brass. If you anneal each reload as we recommend, you will get extremely repeatable and consistent sizing. For the same reason, if you are using a bushing die you may need to check the sized neck diameter. Zero spring back can mean that less sizing is necessary.
Yes, you can treat nickel plated cases just like regular brass, both when sacrificing in AZTEC and when annealing.
Yes. Because AMP anneals the necks to 100Hv, the necks will tend to gall without lube. This will make sizing effort seem greater than usual. With lube the softer necks will be easier to size. Do not use dry media graphite lube.
Your annealer is just fine. As part of best practice, our inductors are varnished to seal all the electronics. You can actually see the process at the 4 minute part of this video: https://youtu.be/lOf4eSIQfi0 The varnish also coats the ceramic insert at the bottom of the inductor. It can give the appearance of cracking, both on the ceramic insert and the surrounding plastic. They are not cracks. Neither of these components are actually operative as part of the induction annealing process. The ceramic is there just to handle radiated heat. It naturally has a coarse finish. The plastic components are just the framework to carry the windings and ferrite cores. Over time the varnish will melt off.
Yes. There are wide variations between brands. We establish the correct settings by micro Vickers hardness testing. Turned brass also requires less power, and we therefore list turned settings where appropriate.AZTEC will automatically adjust for these variations. Any variations should be checked in "Analyse" mode to establish the correct annealing setting.
All brands we have tested can have some lot to lot variation. When starting with a new lot, we recommend using AZTEC "Analyse" mode to confirm the correct setting. See:
AMP is designed to run anywhere in the world. It operates anywhere between 85V – 265V.
The short answer is that provided the case has cooled down, a second anneal will make no difference to the hardness. For more information see this video:
A number of manufacturers polish the annealing marks off the brass, purely for cosmetic reasons. In the past, customers related annealing marks to cheap ex-military brass. That is no longer the case, and annealing marks are now somewhat "fashionable”.
AMP has gained full certification for both Electrical Safety and electro-magnetic emissions compliance to all international standards.
The unit is rated for 750 Watts, but the maximum power setting used in any of our programs is 600 Watts. This is less than a small microwave oven.
The biggest reason for necks splitting is excessive hardness. Because correct annealing keeps case necks at the optimum hardness, they will last much longer with normal resizing and shooting.
Yes and no. Old fashioned erratic annealing with uncontrolled, variable temperatures (and therefore variable finished hardnesses) may give minimal improvement. The main benefit of AMP is to give correct and repeatable neck hardness, and that will definitely improve velocity consistency. This will only make a small difference at close ranges, but once you get out towards 600 – 1000 yards, it will definitely help reduce vertical stringing.
