I’ve had this case gauge for my grendel, since I’ve owned it. I’ve never used a case gauge before, in 28 years of reloading, and have never used this one in the 7 years I’ve owned it. I just read a little bit about it online, and watched a video. I never would’ve guessed what a useful tool it is. It gives you min and max saami chamber measurements, and min/max over all lengths. I was also able to adjust my dies to where I’m not over working my brass now. It’s not a plunk or no-plunk test, it a precise measuring device.
