If I'm loading on the turret, I use auto index. When I take a cartridge out of the shell holder, it's a finished round. The main reason I bought the turret is to take advantage of the indexing feature to speed up the process of loading small batches. If I were using it as a single stage to batch load, I'd be just as well off with a challenger single stage with the quick change bushings, and might have saved a few bucks. The Safety Prime system works fine when properly installed and operated. Takes some getting used to, but it works. I have a few of the Pro Auto Disk powder measures, along with the double disk kits. It's as accurate a measure as my RCBS and Dillon measures with most powders. For those who can't bring themselves to trust a powder measure, there are dies that will go in that extra turret hole that will soothe your nerves, Dillon Low Powder Alarm Die, The RCBS Lockout Die, and the Powder Cop Die. I don't own any of those, but it's an extra measure of safety. To me the speed and convenience of the turret is the main advantage it has over the single stage. It's easy to load 200 RPH on this press, using the auto index. I've got two single stage RCBS presses under the bench, only time them come out is to swage primer pockets on military brass. I have a Dillon swage tool on order, guess that will put the single stage back under the bench for the foreseeable future.
