Thread: whats the best annealing setup available

The base plate with the exit hole in it for the brass should be dished towards the centre, this contacts the brass headstamp surface on its outside rim in one place only, causing brass rotation as the top disc turns, rpm can be governed to allow for a neck anneal only or slower to allow more of the shoulder to be annealed, simple but effective.

Really easy to make on a lathe.

Pedants put too much emphasis on getting annealing perfect down to the last 5 thou below the neck or shoulder, truth is as long as every bit of brass is done the same then they will give identical performance.

You can anneal the neck only for neck tension and brass longevity reasons or include the shoulder for fire forming and concentricity improvements

I have seen some Lapua, Bertram and federal brass annealed half its length, which I think is going a bit too far.
