The critical element in loading for long range accuracy is standard deviation of muzzle velocity. If you roll your own, the easiest way to monitor SD -- and the best way to QC your loads -- is to chronograph them. So owning a chrono is about accuracy. And success, provided you define 'success' as small groups at long range. I shoot over a chrono almost every time I shoot at paper, not out of curiosity, but to QC my work by monitoring my loads' SDs.
