Today if I was buying one it would be the 21st CSS, it's as simple an easy to use as the Sinclair but the indicator is what sets it apart, I have a NECO CAT that I use to straighten those few rounds that need to be tweaked, I would like to add Bersin but right now funds are tight for shooting because I'm getting a Gen2 Prometheus soon. </div></div>
I am always amazed when I read a report like this since I have used both the Sinclair and the Hornady and my experience has been exactly the opposite i.e. I could never get a reproducible reading with the Sinclair but always with the Hornady. Just in case you think I am a newbie to tools, I have 30 years of research experience under my belt.
This is not to slam on Sinclair as I have many of their tools and most are top notch. NECO I also have but it is different than both the Sinclair and Hornady as it can do things that they both cannot do. </div></div>
It shouldn't be a thing of amazement, just your experience and mine, maybe you got a Lemmon and maybe I did, this is an open forum where we all can and do learn from each other, your experience and opinions are no better or worse than mine. IMHO a Concentricity Gauge is a tool that identifys errors in technique, I discovered that I was inducing run out during my sizing operation, I used the Sinclair tool to help me fix it, thru trial n error I discovered that the way I was operating the press induced the run out.
