MD - very nice reasoning behind why I bought and am learning to use the data gained from a run-out gauge. I'm hoping the Sinclair helps connect some of the dots and reveals relationships between dies, brass and patterns of the holes on the paper. I do not own any custom rifles or dies. I have been frustrated in recent years with random flyers in my groups. I've bedded and re- bedded guns, changed scopes, did more case prep, about everything else - except evaluating each step in the load development process related to sizing brass. I'm hopeful the Sinclair and some study will help eliminate flyers and improve my session to session consistency. If not, I'm only out $100 and have added to the experience banks.
