[QUOTE="cjuve, post: 2214304, member: 31341"] I don't use a chronograph for load development I use a chronograph to tell me what my load is doing. Once I have a load that shoots the way that I want it to shoot I chronograph the speeds so that I can calculate drops and diagnose issues related to accuracy degradation. This helps when transitioning from new to once fired brass, barrel speedup, powder temp stability and really anything that would change POI's. for example I recently switched from new to once fired brass in my 6 BR, my previous load of 29.2 grs of Varget produced 2780 FPS with great accuracy. In the once fired brass this load produced 2820 fps with less than stellar accuracy, dropping the powder to 28.8 gr. and lowering the velocity near the 2780 FPS was all it took for accuracy to return.
