I prefer the Sinclair. I also use a Redding case neck thickness gauge, which is a great tool. You'll find that you can't achieve concentric loads if the brass has large variations in thickness. These gauges are one reason I've decided to quit using Winchester brass. Last batch of 7X57 brass varies as much as .004 in neck thickness and you can't load concentric rounds with this crap.

Dave260, I didn't like the Forster gauge and I think the design is flawed. I'm a big fan of all things Forster, except their concentricity gauge.
