I'm in the market for a concentricity gauge. I am brand new to reloading so it's hard for me to see what makes a particular piece of equipment better than the next. After researching it seems enough of you recommend the NECO that I am thinking of buying it. There are some that allow you to correct a cartridge with to much runout right there on the concentricity gauge but not the NECO. It seems that would be very convenient so if you use a NECO or similar product how do you correct runout? Is the Hornady model junk? Obviously some of you think the NECO is more accurate, I'm already sold on that but just have no experience so I don't know how I would correct runout if I choose to buy the NECO??? Thanks for helping a newbie!
