Thread: Annealing

I use an AMP annealer and have noticed that some cases don't change colour at all.So it might be wise to be cautious if relying on a change in colour as the most reliable indicator.
Predictably Lapua and Norma brass are the most consistent but even a change of cleaning method gives different colours.
The option of sending it to someone who uses one of these machines looks like a good deal.
