A couple years ago I bought a Giraud annealer. Every time I use it I am always impressed with how well it works. His trimmer is kick butt also by the way.
I anneal most precision rifle brass every 3-4 reloads. 338 Lapua every other time and 50 BMG every reload.
Below is the hopper loaded up with 200-250 pcs of 6CM brass.
I am using MAP gas so I can cut down the processing time. Doing batches of 500 (308, 260, 243) takes about two hours of machine time. Takes me 5 minutes to load the hopper.
Using templaq, the inside of the case neck got to about 750' and the 450' zone did not extend more than 3/8 or so down below the annealed discoloration.
