Total newb here as I just ordered a turret press a few days ago. I have been reading a lot on the forums and was curious if I could just use a 9mm case gage instead of using a caliper? I have not bought either one yet so was wondering if I needed both. I am only reloading 9mm and its just for range use out of my glock 19 if that matters. Wanna kill these ads? We can help!
