Ninety five+ percent of my handloading for the last 30 years has been handgun cartridges and I have never had a need for a concentricity gauge for my handloads. I was looking at various vendors and at this time I don't care to spend $150.00+ on a tool that I'll use for just one rifle (maybe two if I get bored and measure my Garand ammo). So has anyone made their own? I like quality DIY tools so I might give it a try. I do know I'll have to purchase a dial indicator though...
BTW; have been a machinist/mechanic all my working days and familiar with measuring tools. Just wondering if anyone had any ideas on a concentricity gauge for rifle cartridges.
