What I have learned from these videos about this AMP machine is that 750° is probably too low temperature, and the cherry red used in the past is probably much more accurate. From what I understand the temperature is not that critical either. 950 ° to 1100 ° will not ruin your cases.
The key is getting the heat to the localized area as quickly as possible. The danger is mainly in letting the heat migrate down to the case body. Torches can't get the heat into the neck quickly enough that's why the 750 tempilaq is used, which is lower than the actual anneal temperature. You could potentially go 1100 degrees, so long as it doesn't last longer than a few milliseconds. 750 degrees might require several seconds, which destroys the case because that heat has migrated down to the bottom. So the guys placing cases in a pan of water up halfway along the case body and torching the necks until cherry red are probably ok because they're protecting the head. Anyhow, I'm waiting for my AMP to get here as I trust that method because all the work has been done for me and the machine has the power to heat the neck before the heat gets down to the head.
I ordered one. Greetings from Germany
That’s not what that final group looked like. 😁 But it was still phenomenal.

@rpr6.5 creedmoor You have not understood what I have written.
Pathetic is right. Your asinine comment should be removed and the fact that it has not been is testament to the honesty of the channel.
