I purchased this a few months ago. Decided to wait until I got to Florida to even look at it . Now I'm no authority on annealing.Some say to some say they don't see any difference . I'm not out to say ya or nay but this is so simplified I even feel comfortable doing it . If the programs are correct this has to be the simplest and fastest way to go. . After deciding to run the Aztec mode I installed the correct pilot for the 6 Br correct shell holder and fed the machine the correct code provide from AMP after smoking a piece of brass. It gave me and setting to use for this particular lot and neck diameter pieces of brass . Very simple even I was able to figure it out with just my phone instructions. Yep once getting over the initial cost it's very nice .
