Home Forums Reloading Big Game Rifles Gadgets for measuring case and bullet runout.

Anybody use one of these and has it improved accuracy of your reloads? I am looking at a RCBS case master. Is it decent tool? Any other brand that may be superior?

I`ve the RCBS and it works fine for its purpose. I don`t see much difference in my loads when useing it though. Others claim otherwise........

I use an RCBS tool and Sinclair also makes a good one. Yes, I am a believer. Concentricity makes a difference and the difference gets more pronounced as the range gets longer. I pair the Runout guage with a Bersin Device which corrects runout and the difference is very noticable at distances over 300yds.

I use the NECO and Sinclair. Tried the casemaster when they first hit the market. Sold it shortly after trying it's various functions. Concentric rounds will shoot smaller groups if you and your rifle are up to it. Probably won't see any difference with a hunting rifle unless they are really bad.Rick.

I use the Casemaster and have found it adequate to reveal problems with dies and case necks. I get the Sinclair catalogues and will probably buy one of their units one of these days, but with each catalogue there is something new that looks better, so I haven't pulled the trigger yet...

I use and like the Forster Co-ax guage. I like the ability to guage case neck thickness variation also.
